English: American Optical is one of the contractors that builds milspec Aviator sunglasses for the American pilots, in fact they were the original contractor in the '60s for the product. They are identical in shape and similar in build quality (due to milspec) to the current Randolph Engineering Aviators made famous by Mad Men, but can be found on eBay for a mere 30 to 40 dollars. Comes in a usable case with hard back and velcro closure.
