Thanks for the input so far. The camera body says 6x7, but that means it could have been mfg over quite a period of years. I will look for the mirror lock-up. From what I'm reading the mirror caused vibration problems at slower shutter speeds.
Is the seal under the prism the same stuff as seals used on camera backs? Assuming it can be replaced.
