First impression when I saw a thumbnail of this camera
was that it was a regular Kiev-4/Contax fake, but on a closer look it seems much more interesting.
For a start, the meter, the body of which is the high-profile Contax III/Kiev-III-IIIA type, has a perforated flap, implying dual-range, which I have not seen before. The meter scale is unlike any Contax or Kiev. The meter knobs, viewed from above, appear identical to the Contax IIIa, but not quite identical to the Kiev-4: the red numbers on the shutter-speed dial of the Kiev meter only go to '8'. The shutter speed ring is also much deeper than any Contax IIIa or Kiev.
I thought at first that the focus-wheel looked like Kiev, but the pictures of this are not too clear, and there is no sign of flash-sync, so giving it the benefit of the doubt, my best guess would be that this is a conversion on a genuine Contax III (J.75934). Can anyone say where the metering parts came from?
