By The Chas Fischer Spring Co. Excellent frames with only minor wear to the plating on exposed edges. These have the improved 'streamlined' vents on the frame, common to most by this manufacturer. Stamped 'AN6530' and maker's details. Fitted with excellent clear glass lenses. The rubber cushion remains supple and whilst undamaged does have some surface marking/crazing - see photos. The chamois backing is really quite clean indicating little use. The strap is also in good order although the connectors have light surface corrosion. A good to good '+' used pair. Stock code G21047.
