I got the rear standard of a given-to-me-for-free-albeit-in-horrible-condition Cambo SC completely rebuilt and refinished. Now it's time to start on the front, and to clean up the main rail. Most of the painted surfaces are okay, but all of the fasteners and bare metal areas are showing rust/corrosion, so I have to take everything apart, clean it, de-corrode it and then repaint whatever needs it. I think some people will say that it's a camera not worth rebuilding since a good one only costs about $150 or so...but I had all of the supplies I needed, already, so I currently have $0 invested in a decent 4x5.
