SN 7109864. Lens has Konica AR mount. Lens has been used, but it looks OK. Front Glass is free of scratches. I don't see any haze inside the glass. But glass has some fungus inside, that looks like webbing. Luckily fungus is at the rim and doe snot show up in pictures. Lens still makes very nice and sharp pictures. Filter rim is bent, but lens accepts filters OK. And it will be mailed with Sunpak UV filter. Focus works good. Aperture blades open and close properly. Aperture is snappy. Lens has no other issues other then fungus webbing inside. I will mail lens with both end caps (bothe generic, not original) and 55mm Sunpak UV filter.
