So it's a repro camera, could you show a picture of the film end. I'm assuming the cut sheet film would have been held by a clip or clips.
Presumably it was originally on a set of rails so it could be focused at a set magnification factor. Sort of a mini gallery camera.
I wonder if there was provision for a dot screen filter, for half tone reproduction?
You should be able to do some pretty wonderful 1-1 pictures with this.
