Anyone know if the Grafmatic 2x3 can be used in a Busch Model C? There's a Model C in a local shop with no film holders, so I'd need to get some, but I thought the Grafmatic would be nice if it would work.

If it won't fit then a flat washer, .020 to .030 inch thick, can be put between the spring and body. This will increase the distance from the body that the focus panel can be pulled without causing too weak of pressure against a film holder inserted into the camera. A longer spring retainer screw may be needed also. Its not difficult to make new springs that are a little longer.
