By golly, I guess I must remember them too -- was just fumbling through a closet and found two telephotos I used with my Konica FP "back when."
A 200mm f4.5 and a 105mm f2.5. I thought they were T-mount; had adapted the 200 for an FD mount, but never did much with it. The 105 is missing its adapter and the one off the 200 doesn't quite want to go on the 105, so maybe they're "not quite T-mount."
