I think I'm mistaken. This is for a 00 shutter, not a 0 shutter, so I don't think it will work. Even if I were to drill out the board, the shutter will likely not fit in the recess. But thanks again for posting.
If someone is interested in the 47/8 Super-Angulon I'm selling and needs a Tech 23 lensboard for it, that would be perfect, because it's in a 00 shutter.
A Copal/Compur #0 lensboard should have a hole that is 36.4mm, which is the one I need.
