Schneider Tele-Variogon F4 80-240mm M42 Pentax Screw Mount Zoom Lens
This is a rare big metal zoom that has excellent optics, smooth action and really burly construction (this thing is heavy).
This lens has moderate cosmetic wear and very operation.
The glass has light haze on a couple of internal elements. I believe that it is cleanable but it would be a job to open the lens up.
It includes the shade and rear cap and comes in the leather case.
