I'm wanting to start shooting LF when I get a few more supplies, etc but I'm short of plate/film holders for a couple of very old cameras. If anyone has 4x5 or 5x7 film holders handy, would they mind measuring up the outside width&length? -That is, the part that slides into the camera - which means minus the length of the bit that holds the dark slide. All I have to go on is the size of the GG back for each camera: 4 1/8 x 5" (104x127mm) 5 3/4 x 7 3/8" (145x187mm) I'm guessing I can pick up some 4x5 and 5x7 holders on ebay and modify them without too much trouble. Alternately, if anyone has film/plate holders for sale to suit the half/quarter plate Goerz Anschutz cameras, let me know!
