Lens board Copal size for lens?

[Candlejack]

Hello, I was wondering if anyone knew, or knew how how to find the copal size for a 85mm f3.5 Wollensak in a Alphax shutter? I also need to source a retaining ring for it.
Thanks!

I believe that lens fit into an Alphax 3 shutter. That has a size of 30mm/1.795 inch. I don't think there is a copal equivalent as far as I know.

Here some pages that may help

Wish you luck and please share if you find anything.

SK Grimes site has a page on measuring your shutter’s threads, which has come in handy, plus they can make you whatever you need if it’s an odd size.
