I have a flourite airspaced doublet lens for cell. I think it's the objective for Kowa scope. about 77mm in diameter and fl about 480mm. The only problem is I don't know what's the designed space between two lens. I tried different spacers and found 1mm would be the rough number. The lens has some dusts and a few small scratch near the edge but still in good shape and it's multicoated. Maybe you can find use for it and make a small APO. Selling it as is. $115 shipped. Best Regards, Gu
