260mm f/10 NIKKOR-Q lens. OK have had this lens hanging around for maybe 20 years. Aperture goes from f/10 to f/32, Front and rear elements stick out and past the front and rear rims (Lens caps are convex in order to clear the glass). Quote from S K Grimes website: Mounting in a "Copal #3 Expensive – Risk lies in cutting lens out of mounting bracket". Research indicates that it "has an 800mm image circle at f/22, and can illuminate 11x14 or 12x20". I believe there are 2 versions of this optic: one can be mounted in a Copal #3, the other not.

Has anyone out there been able to practically use this optic or have it adapted to a shutter?
thanks
