Does anyone know who would have lensboards for a Crown that would fit the Copal #1 shutter(41mm)? Also is it possible to get a cam for a 210mm lens for the top mounted rangefinder, and a distance scale.
I have a new lens coming soon and just realized I can't mount it.

I usually cut the hole my self (easy if you have a drill press). But to find one with the right sozed hole, I would check KEH, Pacific Rim or Midwest. They generally have a good selection of lens boards on hand...
