I have a Busch C that takes all of the 2 1/4 x 3 1/4 roll backs, Grafmatic and sheet film holders. I converted it from the spring back to a Graflex with Graflok. It doesn't have a revolving back and cams for different lenses but it's a very nice camera and is light.

If my pockets were gunny sacks I'd have a full line of Ebony and Horseman.
