Bracelet made from a WWII US Army Air Force Bombardier qualification wings badge or pin. You can see where the pin was removed from the back. These were converted to sweetheart bracelets during those times. 

It is not marked sterling, but I did acid test it and it is setter. in The clasp is classic from the 1940s. Chain is heavy and has repairs and kinks, but is a perfect piece of history.

Measures 7” long and the wings are 3 1/4” long. Weight: 30.8 grams. Beautiful patina.
