I recently picked up this beautiful set of sweetheart jewelry. It’s a sterling silver enameled pin with the 17th Airborne patch on it, and under it U.S.A., attached with a gold (colored?) chain to tiny sterling silver jump wings.
The 17th Airborne pin is marked Whittemore & Co. – Attleboro, MA. The jump wings are really tiny, even smaller than common sweetheart jump wings and are marked STER. (Sterling).
