Repairing a Mamiya RB67 120 ProS back. A bit of rust needed to be cleaned from some parts and the release plate spring was broken. To access the spring, most of the mechanism needs to be disassembled. But at this point, everything gets cleaned and lubricated.
Many years ago, when commercial photographers used film, I had a repair account that had around one hundred Mamiya Universal cameras being used in the field at any given time (being used in showrooms by so called “camera girls”) each with a ProS 120 back. So I have seen just about all issues that can come up with these backs and still have a large stock of new parts.
