Free to good home, I have a grip which appears to be for a Mamiya Press 23. It has a crack in the upper rear that is flush and doesn't look to affect use, and an old repair in the front done with some epoxy. The release cable is in good shape and operates smoothly. Strap is old, but pliable and intact. This version does not have a cold shoe. Mounting stud and coupling ring are intact and in good condition.
I can post pictures a little later, or else PM them on request.
Free for cost of postage to anywhere on the planet.
If you want this shipped to the space station, you'll need to make your own arrangements, but I'll mail it to the launch point for free.
