This is a vintage mirror lens with a relatively fast maximum aperture (most that I see are f8). Note that this lens is Non-AI, it will not mount/index on any modern camera without an adapter.
It is in excellent condition with light wear and works perfectly. The glass is clean and scratch-free with no haze, fungus, nor other issues. The focus is smooth.
Lens caps and the leather case are included.
