Nikon 360mm f9 Apo-Nikkor

This Nikon 360mm f9 Apo-Nikkor is a shutterless large format process lens with enough coverage for 8x10. In excellent cosmetic condition, with minor paint wear; there's a touch of dust in the optics, but no hazing or fungus. The 11-bladed diaphragm moves smoothly. The 4" rear flange is pre-drilled with eight holes: four original countersunk holes and, inexplicably, four other "DIY" holes offset by about a centimetre. Either (or both) sets can be used to easily secure this lens to a board (not included.)
