No instant-return mirror on the 1958-60 Voigtlander Bessamatic either. The camera has a leaf shutter mounted behind the lens.
You have just established the most up-to-date collector value of this camera. How much did you pay?
The Tower 32A and 32B are rebadged Mamiya Prismats from the early 1960s:
They're not particularly rare or valuable (at least in the US since they were marketed by Sears). The prices in the eBay auctions noted above are on the high side from my experience. However, one of the normal lenses available was the somewhat rare Canon OM 50mm f/1.9. The lens mount is essentially an Exakta bayonet with the semi-automatic diaphragm mechanism moved from the camera's left side to the right side and built in to the body. By the way, Rick, the Exakta VX mentioned by StephanA is a post-WWII version of the first significant and successful 35mm SLR introduced in 1936. Exakta's first 35mm SLR with an instant return mirror was the TL1000 introduced in 1967.
IC- RACER: I paid about $10 complete. I buy 'deals' and sometimes either the public or even dealers want to simply get rid of stuff. I am lucky to live in an area that has probably the greatest concentration of cameras in the whole world: the NYC-PHILADELPHIA area. - David Lyga
