Vintage NOS USAF US Air Force Pilot Wings and 37 similar items

On OG green cloth about 2" x 4" an embroidered USAF pilot wings of some vintage. Unused, NOS ("New, Old Surplus or Stock) and of significant but uncertain vintage. Look to me like they might be anywhere from the fifties through the seventies. We have multiples so you probably won't get the one used for the photo but they are all the same, official USAF issue. These would have been sewn onto the flight suits over the left breast pocket.
