I'm looking for a lensboard for my Toyo 45G This would be the larger (158mm) type square board for studio cameras. I need the mounting hole to fit a Copal #1. Diameter Specs for that should measure about this: 41.6mm -or- 1.638-inches -or also- 1 5/8" = 1.625 standard drill size. I can pay via paypal. I am in Delaware. PM me if you are selling. Thanks!
