Unlike the recent flange-related thread in the Resources section...I don't want to pay top dollar, and wait a month - for a one-off. I just need the proper flange for my recently purchased 120mm Rodagon WA, as the flange I received with it...while it is the proper diameter - is of the wrong thread pitch. Actually there is enough engagement, without thread damage, to make it work - but long term I'd really like the proper flange!

Lens itself is mint...got a great price...and I do not want to contact the seller and invite a morass of time and additional shipping back and forth.

Thing is...I'm having a heckuva time even finding any reference to what might be the proper flange for this lens. The existing Rodenstock literature lists WA Rodagons only up to 60mm fl., and not to 120mm. Anyone? (Bob?)
