@eli griggs From what I just read last night on the
Soviet Cameras site, Fed was making
Leica copies several years before the War, and the Leitz factory wasn't plundered as completely as the Zeiss ones, so it's hard to be sure (especially without the ability to examine the camera hands-on, with magnification available). Lack of an RF eliminates one way to tell if it's a Fed marked as a Leica would be to
check the RF coupling mechanism -- from my reading, Fed uses a slightly different mechanism from Leica, such that some recalibration is required to interoperate Fed body with Leitz lenses or vice versa.
If it's actually a Leica that's turned up in Ukraine without provenance, it'd be the bargain of the decade, at least. It's priced not much above an Argus C series. Scale focus, of course, but I've shot hundreds of frames with scale focus and generally good results (a bit hit or miss with wide open close-ups, of course).
