1940s Sweetheart Locket Expansion Bracelet Inititals E.G.

This is pretty little gem from the 1940s, when soldiers going off to war would give them to their “sweethearts” with their picture or a lock of hair inside. This is hallmarked “PATENTED” on the inside. This is a well loved gem. I believe the calligraphy initials are E.G. You can see from the picture that there are many blemishes, scratches, gold plating scratched, missing, etc. There are a couple of places where the links are in need of repair. However, they do line up, and there are no missing links. It appears to need a couple of pins to reattach them. With some TLC, this lovely bracelet can be a “new” piece for someone special! From my research, I believe that the face is most likely gold filled, and the rest gold plated. I am not 100% certain, so please take that in consideration. This design does match one of the designs of Carmen by DFB, Co, but it does not have that hallmark. It may be a 1940s contemporary reproduction of that line, as it was popular.
