This is a fast tiny 500mm mirror lens. I haven't seen mirror lenses with aperture rings before, the ClearView allows you to stop down from an f8 through f16.
It is in excellent condition with light wear and works perfectly. The glass is clean and scratch-free with no haze, fungus or other problems. The focus and aperture are smooth.
Lens caps and a rear mount UV filter are included along with the nice metal lens shade.
