Fungus in glass. Shutter and meter working well. Japanese 35mm SLR with fixed lens. Auxiliary lenses were available for this camera. Looks like the Dekon Sr. made by Tokyo Kogaku for DeJur.
Leather needs to be glued down on front.
First Nikon SLR and the first Japanese camera to use a porro mirror. Unusual in that both the shutter and meter are working. Version with chrome trim and coupled rangefinder. Chips out of vulcanite covering over screw heads. Focusing knob turns, but front standard does not move.
