This sale is for a very rare, brand new in box Mamiya 645 / RZ67 External Battery Case to fit all Mamiya 645 and RZ67 cameras. It is unused and obviously has no signs of use. It is supplied complete with original box (which for some reason has been taped down the edges) and instructions. The instruction sheet can of course also be downloaded from this website.
This case is designed exclusively for the Mamiya 645 ad RZ67 cameras for use in cold weather. It allows you to keep the battery inside warm clothing where your body temperature can maintain the battery voltage. It takes the same 6v battery as used in the camera.
