I picked this up in sort of half-finished condition on ebay recently; basically it arrived as a black box with an elegantly designed but poorly executed (light leaks!) mechanism to hold the film holder in place. I've hacked together a temporary usable pinhole camera out of it, but I have a bunch of ideas for making this a really slick & usable machine once I have the materials and time. Here's the ghetto, electrical-tape to fix light leaks, ~75mm 4x5 pinhole camera 12-shooter based around the Graflex "bag mag". The magazine holds 12 shots of 4x5 film and seems pretty easy to use once you learn to work with its idiosyncracies (which involves carefully sliding individual holders out into the attached leather bag, then re-inserting them at the rear of the stack).
Front. The back is centered in the box, I just shot it slightly offset accidentally so it looks asymmetric:
And rear, opened up, with a film holder "septum" in hand:
Oh, and it's got a red window for checking the numbers on the back of the film septa:
The tripod mount is just a tripod plate with the thumb-screw removed, attached to the bottom with wood screws. Fortunately I have another plate for my other cameras.
The modifications I envision are:
1. Slide-in film back & matching ground glass (right now it's semi-permanantly attached)
2. Zoom & focus mechanism
3. Pinhole turret with a big hole (blurry but bright) for composition and different taking pinholes
4. A better lens board holder. I just taped my pinhole board on so that I can go try out the graflex back tomorrow.
And maybe, just maybe, a provision to use a small light glass lens as well. I had one that would have been perfect but sold it last month before I picked up this project.
