So the camera is a Century No. 6.

The back looks like it's designed to take other backs of different sizes and has some sort of movable masks for taking multiple shots on a single sheet of film.

To make it usable, I suspect someone would just remove the back and build a back to take modern filmholders. The maximum size is probably 11x14".

The lens looks great. You could get good money for it on eBay or here in the classifieds.

The camera is going to be a hard sell, since it doesn't have a terribly workable back, is heavy to ship, and needs bellows replacement and a certain amount of general restoration. You could keep it around for ornamental purposes, either on the stand, or some people turn them into coffee tables by putting them on the floor with a sheet of glass on top.
