It was a common problem with
the old screw-mount cameras — you could often see the film perforations in
the edge of the image.

  I had a IIIc that showed the image in the sprocket area.  A local Leica
buff and amateur repairman fixed the problem by installing a spacer on the
bottom plate to push the film cartridge further up into the chamber.
Apparently the earlier cameras were designed for use with the self-loaded
cassettes.  Factory loads came on the market in cassettes that were shorter
than the original Leitz self-loaders.  These factory cassettes could slip
down enough that the image is shot slightly on the sprocket area; at least
that was my experience.
