[pure-silver] Yashica 124G (was Death Valley Days..... film problems)

My 124G (bought used, circa 1992) always offered terrific resistance when 
closing.
Some years later, when it developed a another problem that I actually needed 
fixed, the
repair guy fixed that, too. Ever since then, the locking knob has turned like 
butter.

I don't know whether that has anything to do with your problem. I've never used 
220 in
mine. But difficulty turning it closed is an annoyance you can get fixed.
