Nippon Kogaku 85mm f1.8 Nikkor-H &nbsptype_Audio 0x version for full-frame sensorsThis is an early Nikon 85mm f1. 8 Nikkor lens, from when they were still calling themselves Nippon Kogaku. It's a pre AI lens, as you may have guessed, so its compatibility is somewhat limited. But it's in good working order, with some internal dust and smooth mechanical action. There is moderate cosmetic paint and finish wear, but nothing too dramatic.
