<p>Hi Walter! Does it look like this one?:<br /> <br /><a href="
/> <br /> I think this is the only M42 camera with a non-removable waist level finder. The Biotar lens would go with this or a Contax/Pentacon, both East German cameras. Also, it was a common practice for US camera stores to private label East German cameras, often defacing the original name before gluing or riveting their nameplate on top. This was done with Prakticas, Praktinas, and Pentacons that I can think of offhand. Here is a Pentacon that's had that done to it:<br /> <br /><a href="
/> <br /> This was generally done in the early-mid 1950s. Pentax adopted the M42 mount in the late 50s, the Olympus FTL not until 1970 or so. It became very common on Japanese cameras in the 60s: Ricoh, Fujica, Yashica, Mamiya, Chinon, I'm sure a few others that aren't coming to mind. But this was all after the rebadging days, and I don't recall that ever having been done on a Japanese camera in any case.<br /> rick</p>
