Lens has been used. It looks very nice. But it has problem with the fungus webbing in the front. I see couple spots that are at least 1cm wide. Other then fungus, I don't see anything damaged on the exterior.

Filter rim looks good and it accepts filters. Front Glass does not have any visible scratches. 

Lens works without any issues. Focus works good. Aperture is snappy  and free of oil. Please note that fungus doe snot affect image quality. Lens still works good.
