Older Componon S mount to a LPL disc?

[JR Steel]

My Schneider 135mm Componon S has 42.5mm threading as best I can measure. My LPL 4x5 enlarger has 39mm lens disc. How can I adapt these?

Hi Jim, you can buy a 42mm threaded lpl lens disc that would fit.

Yes, I agree that a new mounting plate would be the way to go. There are not that many top line 135mm or 150mm leneses with a 39mm mount.
