Chrome Omega D lensboard. Has 32mm mounting hole (unthreaded). $8 plus shipping.
Also have a 75mm f4.5 Wollensak Raptor enlarging lens. Would be in excellent condition if it didn't have the 3 small spots of fungus (at least I think it's fungus). The lens is free. But $5 for the retaining ring if you want it.
