Pentax SP black 35mm SLR film camera, a classic model released in 1964 with over four million units sold worldwide. Tested and working, with shutter operation confirmed from bulb through slow and high speeds and proper shutter curtain movement. Film advance and counter work correctly, and the self-timer operates as intended. The light meter responds, though its accuracy has not been verified. The prism shows broken-line corrosion across the center of the viewfinder, which is visible but not overly distracting when looking through.
