This is a 6x9 format, 120 film camera from the 1950's that I modified to be a pinhole camera.
The pinhole is 200 microns, and the focal length is 120mm. This gives an f-stop of f600!
The camera has two view finders, one for vertical shots, and one for horizontal shots. It also has a shutter that can be used in 'bulb' mode, or in 'instantaneous' mode. A cable release can be used.
Here are some images of the camera:
Here are some images from the first roll of film (the pinhole is off center!):
The exposures ranged from 51 seconds in good light to up to 10 minutes in poor light.
These were shot on Kodak Tri-X 120 roll film, and were processed for 9-3/4 minutes at 68 degrees F. in D-76 1:1.
