I know it's a long time since you asked this question but I may be able to help. I am currently overhauling a (mechanical) model 912S and many of the components and mechanisms are similar (if not the same). I could share some notes with you, if useful. John Green (Norfolk UK)

Hello - I have a 993S comptometer that I 'won' on e-bay that needs repairing and servicing.

There was a college in the late 60's/ early 70's on Castle Gate Nottingham 'Sumlock House'. This is where I was taught to use a comptometer. However since decimal currency - and calculators taking there place, it is no longer there - but I am sure there must be a few retired mechanics in the Nottingham area who used to do all the repairs for the college and outside customers. If I don't get a reply from a web site where I have asked if they can help - I will be putting an ad in the Nottingham Evening Post.

I have seen your request - and would hope that if either of us received any information - that we could keep each other informed.

my e-mail address is Marion.chapman2@ntlworld.com

thank you Marion
