This Bronica C2 is in excellent working conditions. I installed new light seals in the film chamber. Ran a roll of 220 through with no light leaks. Glass is clean and focus is smooth. Like most ( all? ) of these Bronica cameras the mirror foam may be deteriorated. Shooting stopped down isn’t affected by this. If you can contact Frank Marshman he is the guy to get in there and install the mirror foam. Price is $215 shipped with fees included.
If someone is mechanically inclined, then yes, it's an easy fix. Maybe install new mirror and ground glass. Rick Oleson has ground glass and I think instructions to install the foam as well. Contact him and ask before assuming I'm right.
I looked on the Oleson website. there is no evidence of a Bronica screen replacement for a C or S camera. I sent an email tonight and he might respond tomorrow.
