Very nice pre-owned Anglo American sunglasses/frames. Style name 'Quadra' BLK FR. 52-20-140. Made in England. Matte black light weight acetate with barrel hinges. Lenses are dark with no obvious scratches. I'm wondering if this type of matte finish frame can be conditioned. The black seems softer in color at some handling points, like the temples and there’s some scratches on bridge. See video. Flush rivets. Please read all the measurements below and compare them to a pair you already wear for size comparison. Refer to diagram which shows you how to measure yours, it's where I measured these. Just relying on your eye size or stamped size NEVER indicates a sure fit. Space between the hinges is VERY important for a good fit too.
