WTB 42mm clear lens

Looking for two 42mm diameter Clear (No magnification) lens - prefer CR93 Acrylic. To suit a Champion 42001 Lens Holder (but any 42 diameter lens should work).

Champions Choice are out of stock.

Any suggestions on other sources in USA?

Or if anybody happens to have some sitting around - I will buy. Please PM me.

Thanks.

PS. I've got several 42mm corrective lens that I would be happy to swap if of interest. +0.75, +1.00, etc.
