This sale is for a near mint Mamiya RZ67 Pro II 220 back suitable for use on any RZ67 camera – Pro, Pro II or Pro IID, giving 20 6×7 shots on one roll of 220 film.
This back has only minimal signs of use, just not quite as new. It is in mint condition other than a thin scuff around the film advance knob probably caused by a ring on the users finger. Tested and in perfect working order, including the dark slide and protective rear cover. A superb back!
