This sale is for a near mint condition RZ67 Pro 120 back, suitable for use on any RZ67 camera – Pro, Pro II or Pro IID.
This back has minimal signs of use, just a couple of tiny paint chips on the edges. Not quite mint but very close. The seals are nearly new (replaced October 2020); they are in great condition (see photo 5). It has been tested and is in full working order, and includes the dark slide. You will not find a better example in a hurry.
