National Calculating Service
& Sumlock Comptometer Colleges
In Britain, Sumlock Comptometer Colleges provided training for operators of the "Comptometer" type machines. These taught the most efficient ways of using these full-keyboard adding machines, shortcut
methods, and techniques for performing more complicated calculations.
They also operated a National Calculating Service which could provide calculating resources for companies, as explained in an advertising feature of May 1967:
MAYDAY Send for Anita!
A nation-wide calculating service for emergencies and routine operations
ONE DAY last May fire broke out in the Co-operative Retail Services store in Bristol. Although there were no human casualties, the Statistical and Wages section with all its calculating equipment was destroyed before the fire
could be controlled. But it was functioning again within 24 hours. Hard on the heels of the fire brigade came the local centre of the Sumlock-Comptometer National Calculating Service, offering the loan of 20 Anita
calculators. The operators were able to resume work as soon as they had been rehoused.
It so chanced that Co-operative Retail were already customers of the service, but if they hadn't been, the offer would still have been made. The service regards itself as being there to help anyone who needs it.
Admittedly, the Co-operative Retail kind of Mayday operation is not its chief function (there aren't enough fires). But it has assisted many clients through less dramatic crises, such as seasonal rushes due to
stocktaking, or staff shortages during epidemics, and in addition it provides a regular auxiliary service to many others, in some cases to the point of forming an external section.
The purpose of the service is to undertake calculating work of all kinds for management and industry, and tasks that it frequently performs include estimating, invoicing, market research and technical
calculating. Most of the work is done on Anita electronic calculators, worked by trained operators either at the Sumlock centre or in the client's own offices. The latter arrangement is sometimes preferred by
clients whose work is confidential. ...
... The service, naturally, is backed by a training scheme. This scheme is a service in its own right, since it provides training not only for prospective bureau operators, but also for the employees of firms using Sumlock
equipment and for people wishing to make a career of calculator operation. There are 31 Sumlock-Comptometer colleges altogether and the full course lasts 15 weeks in order to cover the whole field of commercial arithmetic and
ensure a thorough knowledge of the equipment. This comprehensive course costs 35 guineas [£36/15/-, ie. £36.75] in London and 30 guineas [£31/10/-, ie. £31.50] in the provinces, and trainees who complete it
successfully are awarded the Sumlock-Comptometer Diploma. Shorter courses are also run for the benefit of students who need to specialise in only one or two branches of the work. Firms' own operators often come into this
category, since unlike the bureau operators they are normally employed to do a specific job or jobs, and not confronted with a kaleidoscope of calculations for widely differing purposes.
The colleges also act as employment agencies for those of their students who want help in finding posts, and will continue to act in this capacity throughout the students' careers.
There is a supplementary period of instruction for operators who are to be employed in the Sumlock calculating service bureaux, and the service now employs about 1,000 of these operators in 29 centres all over the country. The
Bristol centre alone has 60 of them, and numbers the Bristol City Treasury and the Port of Bristol Authority among its clients. In spite of the squeeze and the fact that the service was only launched last May (its intervention in
the Co-operative Retail crisis was not only one of its most spectacular operations, it was also one of its first), the 2,000th customer has recently been welcomed on to the books.
The evidence that there was a widespread need for a service of this kind is that in under a year the service has been called upon to answer 2,500 appeals for help.

It is interesting to read above of "people wishing to make a career of calculator operation", which is something highly unlikely to appear in the Situations Vacant column today.
