I recently got a nice deal (i.e.--much less than a Condit punch) on a Kodak Register Punch and 11x14" contact printing frame. I think this setup was designed for some process involved in offset printing or lithography or something of that nature. It also came with a 16" rubber roller in a very impressive metal handle. Eventually I'll probably use it for contrast masking with Ilfochrome or I might try unsharp masking in B&W. The printing frame is in quite good shape, so it was worth the $50 just for that. The pins on the frame are placed such that they would have been about an inch outside the film area, which leads me to believe that it must have been used by attaching some sort of acetate or paper strip to the sheets that were being held in registration. Does anyone know what was used for this purpose, and whether or not these strips are made anymore?
