I recently bought a Zeiss Ikon Super Ikonta C 531/2 with a Tessar 105 3.5 and a Compur-Rapid shutter. According to this page the camera was manufactured in 1950. The thing that still puzzles me is that the lens is stamped"Carl Zeiss Jena". Wasn't it manufactured in Oberkochen, or is it just a brand name that came to be used in the west immediately after WWII?
Though I bought the camera mainly as a decoration item, I plan to shoot with it occasionally, and therefore a coated post WWII lens would be a great bonus.
BTW, has anyone had any experience with some version of this camera/lens? How does it compare to similar cameras of its age?

Many thanks,
