I'm having a film advance problem on my Yashica Mat TLR. Circa 1955? Loading film is no problem. Insert film into lower spindle. Pull to top wind-on spindle. Crank to align arrows. Close back. Wind to #1 in window. Here's when the problems happen. Sometimes it doesn't stop at 1. Sometimes it does. Reverse crank to cock shutter. Push shutter release. Shutter opens and closes as it should. Crank about 3/4 revolution clockwise usually will stop but many times will not. It just keeps on cranking around to 3 or 4. Then I stop and reverse to cock shutter. Release shutter. Then advancing and shooting will be normal for a few exposures. Then returns to hit and miss. This camera is usually reliable and in good shape otherwise. Any suggestions? Thanks.
