I traded an APUG member some unwanted stuff for his unwanted stuff. Ends up I had a 50mm Nikkor and not a 75 like I thought, so this is unneeded. It's in great shape, includes the bubble. Aperture and glass and cosmetics are all clean and clear. Serial is 827229. I'd be interested in 35mm Tri-X, Acros in 120 or 120 slide film.
