Hey guys,
so I had what I came to know a pretty common problem with my M6. The rewind lever would get stuck mid-film rending it impossible to advance the film. The problem was that one of the screw-in plate under the rewind lever was loose. So I tightened it but the problem is that if it's tightened rotation of the lever is not smooth. I feel resistance like every 180° - see video.
Have you ever experienced a similar problem? Send it for repair or DIY?
