By American Optical. Very good frames with only light wear to the plating. These have the short tubular vents. Stamped 'AN6530' on the centre hinge. Fitted with only one clear glass lens in good condition - the right lens is absent but we can supply/fit mint new old stock American Optical glass lenses (clear, green or orange) at extra cost. The one piece rubber face cushion is heavily cracked with some splitting aorund the lens holes. The backing chamois has average soiling and the strap is a bit soiled but retains elasticity. Metal stap components are all very good. Great frames and a good strap but the face cushion really needs replacing. Reproductions are available. Stock code G23306.
