If you buy a precision camera that's around fifty years old that's probably never been serviced, I think it's naive to expect it to be in perfect working order any more than it would be a car of that age to expect take on the road without some attention.
Yeah, but what the OP describes I would expect KEH to indicate as "speeds off" or "slow speeds inop" or the like. It seems like a return is justified, though they're such nice cameras that it might be worth getting a CLA instead.

The lady of the house has to be a pretty swell sort of person to put up with the annoyance of a photographer.
