This P405 back is in excellent condition... It uses 3.25 x 4.25 type 100 pack film (which Fuji still produces). I'm just not shooting much any longer. Asking $120 (includes ConUS shipping & PP fees if used).
Going to have to google for a way to make something work, or find a Graflock back. I've got a Speed Graphic, and a Busch Pressman. Both are spring backs, though. I'm loving the effects I see around the net, using the negatives from the color film.
I've never come up with a back to work with the Pressman, mostly because of the rotating feature. I'll look in my boxes of photo stuff & see if I have any of the Polaroid version of the Graflock... Not the ideal solution, since it doesn't easily allow for the focusing glass. I'll let you know what I find.
