LPL/Saunders lensboard for 150mm Componon-S lens

I must have an older version of the Schneider 150mm Componon-S lens, because the 50mm lensboard is too larger for the threads. I believe a 42mm board may be the correct size, but these seem to be out of production and are really hard to find, at least on ebay. Can anyone recommend a shop that can make a suitable board for this lens? I'm in the Philadelphia area.
Thanks!

I just went throught the same thing.

I have a Saunders 4550XLG and bought the same lens

The only place who had one was KHB Photografix.

Try them.

KHB still has these in stock

I just purchased the 42mm board from KHB. Problem solved!
Many thanks, David.
