Old sterling silver ASF U.S. Air Service Force award pin badge.   Marked sterling on the back and A.E. & Co Utica, N.Y.    Measures roughly 2 1/8" x 2 1/8".   I do believe one strip was earned with the other 2 to be earned? Some surfaces scratches In good condition.   I don't clean items I leave the original Patina on it. I have other collectibles in my eBay store and feel free to take a look.  Once again thanks for taking a look.
