Hi Justin, I have a P21 for Mamiya AFD. It has 2040 shots on it, and I have all the original stuff that came with it, including the case. I bought it last March from Dave Gallagher.
You can call me at 651 224 2389. I'm in the twin cities.
Looking to purchase a P21 or P30 for the mamiya AFD mount.
If anyone has one or knows someone that wants to sell theirs, please contact me!
