Asahi Pentax 'AP' 35mm SLR

The 1957 Asahi Pentax was the first Japanese SLR with fixed pentaprism viewfinder for eye-level vision. It has been acknowledged as the world's first SLR with a right-hand wind lever (the Exakta had a left-hand one, while all other SLR's of that era had knob winding systems), the first with a fold-up rewind lever, and the first camera with both eye-level prism and instant return mirror.

This copy is from 1958 (judging by the serial number), and came with the correct Takumar f/2 55mm lens and lens cap.
