This tiny promotional booklet introduces the Comptometer, has a price list, describes how addition and multiplication is done (and very briefly division too), their 3-year guarantee, and ends with a list of many companies that have bought several Comptometers and a list of testimonials. It came with a separate long list of repeat customers.
It is interesting that the price list says that the Comptometer is available not just with 8, 10, or 12 columns of keys, but also with 16.

The booklet does not contain any copyright year but it is highly likely from 1893 because it mentions the Columbian Exposition of 1893, the example of their 3-year guarantee is dated March 1893, and the list of repeat customers says that the Comptometer had been on the market for four years. Note however that there is already another booklet supposedly from 1893 (The Comptometer: The Arithmetic Machine). I've also seen the year 1897 used for this booklet, so it may be that various editions were printed.

This is a list of "Some of those who after having purchased one Comptometer, purchased more of them".

This promotional booklet describes in detail what a Comptometer is and how it can aid in business. As with the booklet above, it was probably freely sent to people who responded to an advert requesting more information. It contains a separate supplement which lists the many companies that were already using Comptometers. Note that this is the U.K. edition - it has London rather than Chicago on the title page, and the testimonials and the supplement's list of users are from the U.K. only.
The booklet does not contain any publication year, but as it mentions the model E it probably dates from around 1913. Adverts from 1910 already mention a booklet with this title, so an earlier edition probably exists.

This promotional booklet describes the new model C Comptometer. It does not contain any publication year, but as the model C was released in 1909, the booklet likely dates from the same year. This was probably a free booklet would be sent to anyone who replied to an advert to request more information.
Unfortunately my copy of this booklet is in very poor condition. It is missing its covers, the front leaf is detached and the corresponding two pages on the rear leaf are missing.

This promotional booklet describes the new model E Comptometer, emphasising the new Controlled Key mechanism that "enforces accuracy". It does not contain any publication year, but as the model E was released in 1913, the booklet likely dates from the same year. As with the booklets above, it was probably a free booklet sent to people (in the U.K.) who responded to an advert requesting more information.

This 16 page booklet was written by Herbert E. Robbins, and sent to many large British firms on the 14th of February 1921. It describes the model H, but oddly it has no pictures of the Comptometer at all and instead has cute drawings by C. Lovat Fraser, a well-known artist who died later that year.

This 16 page booklet is in Italian, and is a direct translation of the English booklet "A Great Step Forward" above. It even has the exact same page layout and illustrations. It was printed for Giovanni Ferraris, which was the exclusive distributor of the Comptometer in Italy.

Here is a series of eight magazine advertisements promoting the first wooden model (1887-1903), which mostly appeared in Harpers Magazine Advertiser, and in McClure's Magazine.
There are also two later magazine advertisements depicting model B or C (1906-1912).
I own physical copies of these adverts, but have decided to not collect any more because I dislike the idea that old magazines are destroyed for their adverts.

This postcard has a Comptometer advert on the message side, while the address side is a standard US postal card with preprinted 2 cent stamp. The advert promotes the Comptometer and like most of the magazine adverts below offers a free pamphlet with further information.
This card was sent to the Lancashire Insurance Company in Manchester, England. It may have been sent in 1889 as it was part of a collection of cards from 1880-89, but I suspect it is actually from a few years later, about 1893 or so. Either way, it shows that Felt & Tarrant were very early on trying to expand their market to outside the USA.

This postcard has a Comptometer advert on the message side, while the address side is a standard US postal card with preprinted 1 cent stamp. The advert offers a 60 day free trial of the Comptometer.
This card was sent to The Wachusett Shirt Company in Leominster, Massachusetts and is postmarked 25 September 1895.

This is an advertising postcard, probably from around 1905, promoting a 30-day free trial. It was printed for Arthur J. De Berard who was the sales agent for the East coast of the USA.

This card promotes the Model F Comptometer with a testimonial from J. H. Snyder, the Vice-President of the Coats & Burchard Company, Public Appraisers and Engineers, who use 34 machines.

Card promoting the Model F Comptometer.

A card promoting the Model F Comptometer. It has a cartoon drawn by Clare Briggs, a well-known comic strip artist whose work appeared in the Chicago Herald and the New York Tribune. This cartoon features his "Ain't It a Grand and Glorious Feeling?" catchphrase.

This card promotes the Model F Comptometer by pointing out that Topping Valuation Company guarantees the accuracy of their figures and that they use exclusively Comptometers.

Another card promoting the Model F Comptometer. This one emphasises the fact that most of the calculations needed in business are additions and multiplications and that the Comptometer excels at that.

This card is in the shape of a Model H comptometer.

A German card promoting the Model H comptometer.

A card promoting the Supertotalizer. There are very few adverts for this model because the electric model K was introduced shortly after and promoted much more heavily.

This Dutch card promotes the Super Totalizer, which it calls the Comptometer model S. Presumably it dates from around 1933 or 1934 since there is no mention of the electric model K. With the reply postcard you could request more information and/or a free demonstration of the ST with no obligation to buy.
This card was addressed to Roos & v.d. Kolk, a large department store in The Hague. This was a chain that had stores in Den Haag, Utrecht and Rotterdam, and they sold everything for in the home, from clothing and prams to furniture, heaters and carpets.
The address of the Dutch Felt & Tarrant offices was then in the Mercurius building, Prins Hendrikkade 20-21 in Amsterdam. See the Dutch manual in the Books section for their previous addresses in Amsterdam.

This Swedish card promotes the Comptometer for use in salary calculations. It has a separate reply card that was stuck to it with a round paper sticker. There is no mention any particular model and it contains no copyright year, so it is hard to tell when it was printed. The Bertil Stenbeck company was apparently founded in 1929 and the picture show a shoebox comptometer, so the card must be from the 1930s. I believe it is more likely to be near the beginning of that decade.

This postcard with a postage date of 12 May 1934 shows a photograph of the Comptometer School at Aldwych House in London. It was sent to Comptometer operators to encourage them to recruit others. The text reads:

Dear Miss Cleary,

Owing to the great extension of Comptometer business we are immediately in need of students to be trained as operators. We are, therefore, continuing to pay 10/- bonus to any operator introducing such students. The course now takes 3 months. An illustrated booklet giving full particulars regarding the School will be sent on request.
Thanking you for any assistance you may be able to give us in this connection.
Yours faithfully,
FELT & TARRANT, LTD.

This Italian card promotes the electric "Floating Touch" Comptometer, also known as Model 992 or 99C.

This card promotes the Comptometer schools, and was included with the 1956 issue of Comptometer Medley.

This postcard promotes the Comptometer Commander, a dictation machine that used a wide mylar magnetic belt.

This leaflet is in Italian, and probably from around 1900 as it promotes the wooden model Comptometer. It was printed for Dino Gatta who at this time was the Italian Felt & Tarrant representative.

This leaflet describes a calculating competition. It took place during an exhibition of office equipment held in the Royal Agricultural Halls in Islington, London, on Saturday June 8th, 1918. It was open to users of any calculating machine, but seems to have been organised by Felt & Tarrant (or actually the U.K. distributor Herbert E. Robbins) as a publicity stunt in the knowledge that a Comptometer operator would likely win. The addition contest was won by Amy Bower, who correctly added 5 columns of 30 monetary amounts (pounds, shillings, pence) in 3 minutes 51 seconds, supposedly a world record. The multiplication contest was won by Mabel Hall, who correctly multiplied 25 pairs of four-digit numbers in 2 minutes and 38 seconds.
In the photograph of the Felt & Tarrant stand at the exhibition you can also see the stand of Burroughs, their main competitor, nearby.

Herbert E. Robbins Ltd. was the exclusive distributor of the Comptometer in the United Kingdom. This sales leaflet describes British Comptometer training schools. Companies who had bought Comptometers could get their staff trained there for free. It was also possible to hire trained Comptometer Operators temporarily to deal with busy periods. This leaflet mentions enlistment, so it must be from the period 1916-1919 when army conscription was in effect.

The leaflet focuses on the large number of repeat customers for the Comptometer. It would have had a post-card attached that you could send back to ask for someone to demonstrate the Comptometer.
It accompanied a letter by Herbert Robbins dated 1st June 1920 which can be seen below.

This is a British promotional leaflet. It is not clear when it was printed as it has no copyright year, but it seems to show the model H, and I suspect it is from about 1925. It would have had a post-card attached that you could send back to ask for more information or for someone to demonstrate the Comptometer.

This is probably a page cut from a booklet, as there seem to be rust stains along one edge from staples. It advertises the model H Comptometer, with decimal or sterling keboards.

A small leaflet from Peacock Bros. who were the sole distributors of the Comptometer in Australia.

This Australian booklet from Peacock Bros. promotes the Comptometer Model H, describes how profits are calculated and the results of a calculation contest. The winner was Miss O'Shea of the Commonwealth Postal Department, who added 56 columns of 30 numbers in 30 minutes.

Large Italian advert showing a photo of Comptometers being used at Edoardo Bianchi, a car and motorcycle manufacturer in Milan. The comptometers are model H or J, but from the style of the advert it probably dates from the early 1920s.

Large leaflet about the model H or J Comptometer. It includes a picture of the Comptometer Peg-Board, as well as a picture of one of the 18 Comptometer schools in the UK. It came with a reply postcard.

This leaflet describes the development of the Comptometer since its inception 50 years earlier. It also mentions the 100 Comptometer schools in the USA and contains a brief description of the new peg-board system.

This Indian leaflet promotes the electric model K, as well as the standard model J and rather unusually the Super Totalizer. It has the reply card still attached. It is interesting that all the photos and illustrations of the Comptometer show them as having a different arrangement of key column colours. The last two columns have distinct colours and are marked As/P (for Annas and Paise) with the other columns marked Rs (Rupees). They also all seem to be painted in the dark model K colour with lighter decorations.

This leaflet was accompanied by a letter from the Indian branch of the Felt & Tarrant company, dated 10th August 1939. The letter can be seen in the letters section below.

This leaflet promotes the Comptometer schools in the USA and around the world.

This leaflet promotes the "Cushioned Touch Comptometer". i.e. the Model M.

Large Italian advertising leaflet for the Super Totaliser version of the Comptometer model M. It seems that this machine was sold and used mostly in Italy, and it may be that it was manufactured (or at least assembled) locally.

Large Italian advertising leaflet for the electric Comptometer, model 992.

In about 1955 Felt & Tarrant diversified by manufacturing a dictation machine. The recording medium was a wide Mylar belt of magnetic tape, called the Erase-O-Matic magnetic belt, which allowed for quick access to any part of the recording just by moving the tape head sideways.

This is the Italian version of the advertising leaflet above for the Comptometer dictation machine.

Large Italian advert for the electric Comptometer, model 992. On the reply slip it also shows the Comptometer dictation machine, as well as a listing calculator made by Walther that was sold by the Comptometer Corporation and rebadged as the Comptometer 202 or the Comptograph 202. As this advert uses the name company name Comptometer Corporation, it probably dates from 1957 or later.

This is a standard mail shot letter. The very elaborate letterhead was printed by the Wisconsin Bank Note Co., Milwaukee. The letter was accompanied by a pamphlet and a list of 101 testimonials.

Gentlemen:-

        If you desire it, we will send a Comptometer on sixty days
trial, providing you will pay express charges both ways in case
you do not purchase it. We make this offer because we find the
Comptometer itself is our best salesman.
        It will not run itself. Like the typewriter it requires a
reasonable amount of practice to enable one to operate it
rapidly, addition requiring more practice than anything else.
Multiplication requires the least. If you will have one person
in your office use it on practical work twenty minutes a day for
a few weeks, he will acquire sufficient skill to make it almost
indispensable to you.
        We especially call your attention to the character of the
101 testimonials, the writers of some of them doubtless being
personally known to you, and the fact that during the short time
it has been in the market, many, after purchasing one Comptom-
eter, have purchased a second one, and in some instances, a
third, fourth, fifth and sixth - see list on pages 14 and 15 of
pamphlet.
        In adding it foots all the columns simultaneously by simply
striking one key for each figure, (except ciphers which are not
struck at all) footing bundles of checks, scattered items and
cross footings just as well as regular columns.
        We know that a Comptometer properly operated would pay for
itself many times over in your office. The only question is,
whether or not you have some one who will take hold of it and
give it enough of the right kind of practice in actual work to
become skilled in operating it, and whether you have or not, can
only be determined by trial. If you are willing to pay the
express, we are willing to supply the machine for the trial.
                       Yours very truly,
                       Felt & Tarrant Mfg. Co.
                       D. E. Felt

This is a hand-written letter from F.W. De Berard to A. H. Stanton in Huntington, Massachusetts. Presumably this was Albert H. Stanton, born 23rd January 1860, who was the town auditor. Note the lack of house or street name on the envelope.
Heywood Bros & Co were a furniture manufacturer in Gardner, Massachusetts.

Dear Sir,
   Request for trial was sent direct
to Chicago from Heywood Bros & Co Gardner
Mass & Compt was sent on 25th.
   Can you go there inside of say, a week
or 10 ds, if so, we will turn it over to you.
   We think they should be seen as soon
as that.
Yours truly,

This is another hand-written letter from De Berard to Stanton, apparently paying him a commission. Smith Hogg & Gardner was a dry goods store and D. C. Percival & Co a jewellery store, both in Boston. It was quite difficult to decipher the writing, but it seems to say the following:

The letterhead has become more sober, displaying the wooden box comptometer and company name. It no longer mentions the Comptograph, as that had been split off in a separate company run by Robert Tarrant. The letterhead also lists the company managers, and shows the cable/telegraph address and the code books that can be used in telegrams sent to them.

          Columbus, Ohio,
Dear Sir:-
          I enclose herewith carbon copy of my letter of even date to

oil that was supplied with the machine.

               Thanking you very sincerely for this order and
trusting you will not hesitate to call on us at any time we
can be of service, we remain

                                     Very truly yours,

This is a letter by Herbert Robbins dated 1st June 1920. The letter is stamped by the Great Central Railway, Manchester, who were presumably the recipients. It was accompanied by a promotional leaflet which you can see above.

                           June 1st., 1920.

Dear Sirs,

   Although you are a customer we think you
will be interested in the enclosed leaflet.
We hope your experience of the Comptometer
is similar to that expressed by the volume
or repeat orders which we are constantly
receiving.

May we remind you that we are at your
service and shall be glad to give any assist-
ance that will enable you to get the best
results from your machines.  As you know,
the more of your figure work you do on the
Comptometer the more money you save.

                       Yours faithfully,
                            HERBERT E. ROBBINS LM.

Dear Sir,

    A large number of Comptometer Adding and Calculating
machines are now employed in businesses similar to your
own, and they are giving extraordinary results, both as
regards direct savings and increased efficiency.

    The economies effected by most firms amount to many
hundreds, and in some cases, to thousands of pounds per
annum.  No change of system is required,the introduction
of the machine involves no disturbance of any kind; while,
if desired, even the capital outlay can be avoided.

    May one of our representatives call and see you?
He would then be able to tell you what other firms are
doing, and could bring a Comptometer with him, so that
you could test it on your own work in any way you choose.

    If our experience with firms similar to yours is any
indication of the economies you might enjoy - and we feel
sure it is - you will realise that the matter is well worth
the attention of one of your principals. Our representative
will content himself with giving you definite information,
and leave you to form your own opinion.

    We enclose a postcard for your convenience, and hope
that you will use it.

                          Yours faithfully,

Dear Sir,

            I thank you for your telegram received
in Sheffield this morning and have pleasure in giving
you the particulars you require as fol1ows:-

        PRICES. Comptometers range in price from
        40 to 92 guineas according to size and model.
        The models usually installed by Co-operative
        societies cost 40 or 69 guineas - the latter
        price machine is that used by London, Manchester
        and Salford, Brightside (Sheffield) and a large
        number of other societies on Climax Check work.

        FREE TRIAL OFFER. Under this offer we supply a
        machine and an operator absolutely free of charge
        and obligation for a period of one or three days
        so that thorough tests can be made of the machine's
        application. Or, if preferable, we hire machines
        for any period up to thirteen weeks on the under-
        standing that if the machine is purchased during or
        at the termination of this period, that all hire
        invoiced or paid is debited off the purchase price
        or credited. Under this method of trial we train
        clerks free of charge and do everything in our
        power to see that the machine , or machines,
        gives the utmost possible return for its installation.

             I hope these brief notes will be of interest
to you and that you will be prepared to investigate our
proposition for your office and work.

This is a standard mailshot letter. It was sent to Lamson & Goodnow Company, which is a company that makes cutlery, was founded in 1837, and still exists today. The letter is (auto)signed by John C. Nevins, who is listed in the letterhead as the Vice President and General Sales Manager of Felt and Tarrant. The letterhead is almost the same as in 1919, except that it now depicts the model H or J. On the back of the letter are a set of useful calculation tables and conversion factors.

Gentlemen:-

            Buyers of Adding - Calculating Machines -- the discerning
ones -- are more interested these days in the physical proof of what such
equipment will do than in verbal discussion of the machines themselves.

            Why shouldn't they be?  When it comes to making a decision,
proven facts are always better than anyone's claim, opinion or "guess so."

            The chief concern of the buyer, therefore, should be to find
out which machine will do the most figure work for the least money --
all elements of cost considered.

            When you find:
                 How many columns a machine will add;
                 How many invoice and payroll extensions it will figure;
                 How many cost divisions it will make in a timed test on
your regular work -- not a flash demonstration on a few selected items,
but a real, practical test of an hour, or a day if necessary -- then
you'1l have a positive standard of value by which to gage any machine.

                  If you are interested in getting the most for your money
in figure work, call in a Comptometer man for an interview on ways and
means of doing it.  No cost or obligation involved.  See your phone book,
under Felt & Tarrant, or write to us direct.

                                 Very truly yours,

                 Sales, Service and Employment

                          Offices.

            Because of the steady growth of Comptometer sales
in Springfield district, as well as the increasing demand for
Comptometer clerks and trained operators, we have found it
necessary to move into larger quarters.

            The State Building, Room 615, 1200 Main Street,
is the new location.  We feel that our Comptometer School is
as much a part of your firm as ours, and we cordially invite
you to call and see how your future clerks and operators
are trained.

            We want to take this opportunity to thank our cus-
tomers, friends, and operators for their support, which in
reality has made it possible for us to expand our office
twice within three years.

                        Very truly yours,

This is a letter from the Indian branch of the Felt & Tarrant company to the Accountant General of Jhalawar State, dated 31st August 1935.

                                      31st August 1935.

Accountant General,
Jhalawar State,
Rajputana.


Dear Sir,

         We do hope you will find time to look through the
enclosed. The New Comptometer is extraordinary, a great
advance on any calculating machine previously offered.

         The Indian Government is using 350, and the Indian
states 35 Comptometers, with excellent results.

         The New Comptometer gives you absolute accuracy
in all your figure work, it is practically foolproof.  You
can be sure of your figures.  It pays for itself in a few
months.  It saves Rs 2000/- per annum.  It is at least three
times as quick as old-fashioned ways. It keeps your figure

This is another letter to the Accountant General of Jhalawar State, dated 10th August 1939, with tables on the back. It seems that 5 years after the previous letter, the Accountant General has finally become interested in Comptometers.
The leaflet that accompanied this letter can be seen above.

Dear Sir,

     We thank you for your enquiry of 5th August in connection with
the Controlled-Key Comptometer, and have pleasure in giving the
following particulars about the machine, and also to enclose some
literature thereon.

     Briefly stated, the Comptometer is an Adding and Calculating
machine, designed to do every kind of figure work with absolute
accuracy in the shortest possible time.  Its chief advantages are -

     It multiplies 5 to 7 times faster than with pencil and paper
     It makes all additions in roughly one third the usual time
     It subtracts as fast as it adds
     It divides 4 to 5 times faster than ordinary methods
     It prevents errors
     It eliminates the use of paper to a large extent
     It enables work to be kept up to date
     It permits junior clerks to do work otherwise done by more
        highly paid men
     It gives statistics at a time when they are of maximum benefit.

The Comptometer organisation in India is a branch of the world
wide organisation, and is in charge of experts who have been specially
trained in methods of mechanical accounting.  We maintain Schools of
instruction in Calcutta,Bombay,Cawnpore,Delhi,Madras,Rangoon and Colombo,
and use every effort to see that every machine purchased is put into
effective operation. Therefore, although we supply clearly written books
of instruction with every machine sold, we are always ready to train the
clerks of our customers at our Schools, free of charge, or to supply
trained operators.

      We also maintain a Repair Department with a stock of spare parts,
and all machines will be kept in first class repair at all times.  A
guarantee is given with every machine to keep it in good running order
for 12 months from date of purchase, free of charge.
