Mamiya Press
This camera is a one-off that uses a Mamiya Press (Universal, Super 23) 50mm lens and 6x9 film back. Other Mamiya Press lenses could be mounted on the camera. I really like this lens but the Mamiya Press camera is excessively large. With the 50mm lens the rangefinder focusing is really not needed, so I machined a smaller body to accept the lens, back and finder.
