A very nice and affordable homefront item here. I believe that this US Navy badge originally was not attached to a "Son-In-Service" badge, as the chain is looped through the pinback rather than attached from the factory. Both badges have working pins and catches on their reverse, and the USN badge is marked "STERLING."
