LEE L : I bought a Horseman 4x5 back to get the ground glass assembly. The rest of the contraption that I got does not fit on my camera. That would be the frame that the GG back assembly fits on. Perhaps the frame is from a 4x5 monorail Horseman. Perhaps you would want it in exchange for a drink or ice-cream sunday? I'll bring it along.
Thanks. I'll take you up on the offer if it's LE parts. Did you just remove the frame and glass that leaves a Graflok back exposed, press two levers then slide sideways and lift off?
