Mamiya 7II With Impact Damage: Not Repairable

Some cameras that come into the shop I feel are not repairable. This Mamiya 7II suffered impact damage: cracked top cover, rangefinder mostly inoperative, body dark slide curtain moving very slowly or not at all. Before going further, I checked out the body for major damage. As you can see in the video, when the body was put onto a block that fits into the film plane the was some rocking motion (might not be that visible in the video) and to make it more obvious, you can see when the body and block are put under a dial indicator, the amount of play.
My guess is that this impact twisted the body or front plate in such a way as to cause the rangefinder linkages to stick and also to cause issues with the dark slide curtain. A decision was made to not go any further. mamiya mamiya7 # mamiya7II
