A friend has a beautiful old Friden model STW Calculator that stopped working, "top is locked up" is his description. We are looking for a person, group, society, etc in Southern California to assist. Is it possible the machine just broke a belt? Is it possible to try a DIY repair if parts are available? Thanks for any hints. Dave_S

Try to find a typewriter repair shop. They may be able to suggest fixes. An old time tube radio repairman could probably fix it also.

With a mechanical calcuating machine, especially one as complex as those, it's quite likely that the first step is a good cleaning. You're talking about 50 year old oil, grease, dirt, grime, and gunk. :)
I have one like that I haven't tried in years that sort of worked. I had another one that was locked up and I sold to someone who was going to restore it but I never learned of the outcome.

I'd probably start with toothbrushes and kerosene, then move on to lubrication.
