Mamiya 7: Checking a Dropped Body and 65mm Lens

The owner of this Mamiya 7 told me that it had been dropped along with the 65mm lens. First thing I check when a camera has been dropped is the lens and the bayonet flange. I checked the lens (using techniques previously posted) and the body flange is evaluated for flatness by using a dial indicator and film plane fixture as shown in the photos. Five readings are taken around the bayonet ring.The back focus of the mount is also checked.

Other than a rangefinder that needs some adjustment (not uncommon), the camera and lens passed all tests. Seems like the lens hood took all the force of the impact. Lucky!
