I think the camera with which I took these two images was made from the back 1" of a Spd/Crn Graphic, (with Graflok back). There is a plain aluminum plate on the front on which is mounted a very wide angle lens.
The lens chooses to remain anonymous. Other than the shutter speeds, the f stops and the 3 internal filter settings, (yellow, red, other red), there are no markings apparent.
