Retaining ring for Dallmeyer Pentac 8"

[Sam_PNW]

Does anyone know offhand the thread specifications for the Dallmeyer Pentac 8" f/2.9 ? I'm getting some custom lens boards made and this is the only dimension I can't easily measure.

Whoever is making the boards should be able to measure them.

They could, but I'd have to mail them the lens, since they're not local.

So what, you will end up with the proper threaded board with the lens properly orientated.
