Originally posted by Nesster That is strange, though appears the 516 was war time and thus they probably scrounged around for parts... the 6x9 should be a 516/2 based on internet info, and the 75mm lens is definitely wrong... Measure the film opening - it will resolve the issue! I think the 6x9 on the B2 film is just a film designation, not a negative size for this camera.
Does the overall camera look like this?
the 6x9 is quite a bit bigger
First, I have cousins to this model. They take 120 film, you get 15 shots per roll, normal 120 cameras, e.g., Yashica MAT 124G and the SLR medium format camera would give you 12, if I recall correctly. So there is no ' * ' with the serial number, that indicates prior to WWII ending, after WWII ends, serial numbers would have ' * ' indicating that they were made from parts 'squirreled away' during the war. However, when those part ran out, I am not sure of the serial numbering. All mine are post WWII. Interesting side note, My dad's model is newer (relative) to the one I picked up on ebay a couple months ago, which is in meters, my dad's is in feet. Manufacturing ranges for the two (only 209 serial numbers apart) July 1948 - January 1949.
There is a Zeiss Ikon user group on Yahoo, I recommend you join, post the serial numbers of the body, lens, and shutter (they should all have separate serial numbers). There are some really, really, knowledgeable people in that group. As indicated above, they can give you a lot of information about your camera.
Hope this helps.
