I have 2 lens boards for the linhof technika size. One is metal and the other looks to be home made in the right size, made out of a hard plastic like material almost looks like its made out of carbon. It's about 1/8 inch thick and very tough, great material for a lens board. The holes are for a #1 shutter in either compur or copal. The hole in the metal board is offset lower for wide angles. For the both of them I'd like $40.00 shipped or best offer, in USA
