Here is the nice metered prism for the Mamiya 645 and 645 1000s (not the Super, Pro, or Pro TL).
This one is in good cosmetic condition with moderate wear and works perfectly. There is a slight stripe of degradation in the finder (common in these) that is slightly visible while in use but does not impede the function of the finder. The meter does not work, it is several stops off with fresh batteries.
Get a good deal on a nice prism!
