This is a museum quality sterling silver museum quality reproduction of a 3-inch World War II Senior Balloon Wing and is a very truly beautiful wing. This is based on a Josten Design for the basic wing and then someone soldered a star on it to make it a senior rating not uncommon for that era. If you look closely you can see the star was added because it is not flush with the back. A very unusual wing. This pin backed wing is very heavy for a WWII wing.
