Help please. Which enlarger do these boards fit?

They are threaded female M90x1 at the rear, roughly M29x? at the front. They're made of light alloy.

One came from Italy, the other from France. The dished one had a 135/6.8 Beryl, the flat one an 85/6.8 Beryl.

I ask because I'd like to sell them but don't feel right about selling them as mystery boards. I think knowing with they fit would make them easier to sell.

This post is not an offer to sell, it is a request for information.

Sigh. I'd hoped someone would recognize them. Not Durst.

Some Fotar lens boards are round like that. Mine are not so I can't measure to be sure. Jon Wilson or Vinny on this forum might be of some help to measure if they are so inclined.

Erik, thanks for the hint. I'm not sure its correct, the boards I have screw on to something threaded male M90x1, have straight sides, aren't beveled like Durst boards.

Your kind hint got me to this http://www.largeformatphotography.info/forum/showthread.php?62264-Lensboard-for-Fotar-10x10-vetical-enlarger , which says Fotar boards are beveled.

Well, what do I know?:)

Erik, I think that you, like me, are an ignorant barbarian. Welcome to the club.

Y'r hint was helpful.
