I recently picked up a Kodak 2D 5x7 camera and these boards came with it. I'm going to use a universal flange and don't need these, so thought I'd try to find them a new home. Boards are all 4 1/2" square and came with a 2D 5x7 camera. The hole sizes I'm giving are approximate at 36mm, 45mm, and 68mm because they do not appear to be perfectly round. $20 for all three + $5 shipping in the USA. USPS money orders preferred.
