Army Air Corps Heart Locket Necklace Mother-of-Pearl

Vintage WWII sweetheart US Army Air Corps heart shaped locket necklace. Winged propeller insignia in a mother-of-pearl heart. The clasp on the chain is marked 1/20 14K and the inside of the locket is marked 1/20 - 12K G.F. (gold filled, which means it has an extremely thin gold coating, ie. it's not real gold). Fairly good condition with light general wear. The mother-of-pearl heart seems just slightly crooked.
