Specifically need one for a Copal #3 and/or that would fit an #4 Acme Synchro (approx. 2.5" hole). Would also be interested in others. What do you have? Thank you, Bill Barber
I went through that exercise recently. Cambo did not make a board to fit the Acme Synchro so you'll need to have the hole machined larger. Given that, it might not matter what size you start with but cola 3 hole will require less machining htan a smaller hole.
Hi Bill
I have a grey Cambo board with a 2.5" hole. Board is 6 3/8" square. The board has 3 small threaded holes that looks like it had a retaining ring attached at one time. If you are interested let me know
