Nikon Nikkor 35mm f/2 lens with caps (not pictured but have some faith they're there). The glass has some light haze. I believe it would perform fine but a CLA would not hurt it. The focusing barrel turns smoothly but feels dry, not squeeky but.... The aperture ring turns smoothly and the lens stops down correctly. The ring was modified but cutting a notch in it to work with Ai cameras, see the photos. We see this fairly often. It was what people did rather than swapping out the aperture ring. It does work. The lens has been through the wars and shows wear from use. That said, some like patina.
