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:
