This is an original pair of US Air Force aviator pilots goggles made by American Optical. On each corner of the lenses is the AO logo with a upside down triangle and a 1 etched into the lenses. The goggles have lenses with a greenish tint, metal frame and a leather mask and a nylon elastic strap. On the front bridge of the goggles they are marked: A-N 6530. The googles are used with wear such as finish and some pitting on the metal, scratches on the lenses, the leather mask part shows use wear like rubbing, scratches, stains etc. The elastic strap as seen in the photos has bloodstains and other use wear. They may have seen some brutal combat. This is fresh from an estate and they have not been cleaned, as found condition. This is just a superb vintage aviators goggles in great original condition.
