I picked up one of these the other day mostly to get the nice chrome 50mm 1.8 on it. In any case, I ran a roll through it and MOST of the frame showed serious overlap. This camera has a rapid winder on it...before I waste more film, I'm wondering if the problem could be in the rapid winder and not in the film advance mechanism, per se. Specifically, is it possible that the rapid winder is advancing enough to cock the shutter, but not advancing the film I'll the way? If this sounds likely, I'll crank a short roll of expired HP-5 out and see what happens if I ONLY use the knob to wind. I'll also probably go hunting for a regular base plate. The rapid winder is a neat addition, but it certainly adds a lot of weight and bulk to the camera. It seems I can't win for losing with these cameras . This one seemingly has good speeds, the curtains are fine, and there's no vertical misalignment on the rangefinder. Fortunately, at least, my Leica IIIc and Canon 7 do both work perfectly, albeit with the vertical misalignment that seems all too common. I need to just box up all my LTM stuff and send it off for service.
