The thinner one is not marked with a model number, but it *is* marked 5cm on the lens-side surface (which may explain why it didn't work with the Hektor!). My guess is that it goes with an Elmar 50mm f/2.8 SM lens I have; that lens is contemporary with its bayonet cousin (I assume), so that would be a reasonable combination. Its serial number is 1192922; on the camera-side surface it has a four-digit code inscribed: 7938. I don't know much about Visoflex models, but I have some reason to believe that mine is a Visoflex II (it's scrawled onto an import certificate I have). I also know very little about the bayonet-mount lenses. Are the M and R lenses at all compatible? Which is compatible with my Visoflex? Is it possible that the short mount is intended to be used with whichever style my Visoflex isn't intended for?
