I have six lens boards for the Wehman camera, all made by me.
These are not original Bruce Wehman boards, but they all fit and work properly. And they cost less than the originals.
Three blanks, one for Copal 0 (34mm) and two boards with 85mm holes. One of those is spray-painted black.
I was going to make an adapter board out of the black-painted board, but decided to just stick with Wehman boards for all lenses.
$60 each including shipping to US/Canada.
Or buy all six for $300 shipped.
