Broke the camera

In my attempt to remove the prominent vignetting which restricts the scanned area to 5x8 inches, I broke the camera. This was to be expected, as it has happened every time I try to do it (or at least soon thereafter). I can only hope the problem is a physical gearing issue, which means I might be able to fix it. And I hope it does, as I'd love to take it out west and south and other places...
