I was just given a Burke and James Saturn 75 monorail camera. The camera is in l ike new condition. I am told that it is a 5x7 camera, but it has a 4x5 reducing back. It also came with a Schneider Symmar 150/265 convertible lens which is in need of lubrication and adjustment. Since I already own a Technika V, I don't re ally need another 4x5. I am interested in using the camera as a 5x7 and am wonde ring if anyone can tell me how to aquire a new back for it or if it is possible to make one ( as a last resort ). My enlarger is a 4x5 and I felt it might be fu n to experiment with contact printing the 5x7 negs.
