I have a Beseler Topcon Super D body that is dented in one corner, with removeable pentaprism that is also dented.
The shutter fires, and I have tested at all shutter speeds between 1/1000 and 1/2, all speeds have been verified as consistent with each other for exposure at full range of f/stops on lens. I can provide developed test roll showing all shots same density.
Body was $370 (with 50mm f/1.8 lens) when new, and in 1964 is the first SLR on the market with Thru-The-Lens metering. This camera body accepts Exakta mount lenses. They are rugged tanks among SLRs, used by US Navy and US Air Force as cameras 25 years ago.
I can let this go for $90 shipped within USA. On eBay undamaged bodies are listed for $400 even today! I have four of these, so I can afford to let one go at an attractive price.
