Marine Corps Sweetheart Heart Locket Necklace Mother of Pearl

Vintage WWII sweetheart Marines locket necklace. Nice heart shaped locket with the USMC EGA. Nice mother of pearl piece. Overall fairly good condition. There is some discoloration on both the locket and the chain. The inside and the clasp are marked '1/20 10 KT. - G.F.' The clasp also looks like it has a brand name on it. The inside heart pieces meant to keep the photo is place are a little loose. The clasp stays closed, but is a little finicky. You have to make sure it is closed tightly or it will pop open.
