Sears 28mm F2.8 with M42 Mount.  The lens is used and shows average wear for its age.  Focus and aperture function correctly.   The glass has some marks and dust associated with age, but appears to be clear of fungus, mold, and haze.   Includes both end caps.  I mounted the lens on a mirrorless digital and took the photo of the yard art.  The lens functions correctly.  Shipment to the United States only.
