This item is a vintage "Darwin 1938" double pin, sometimes referred to as a "sweetheart pin". It features a circular enamel pin shaped like a lifesaver with green and white detailing, connected by a chain to a small anchor pin. These pins were typically given by service members to their loved ones back home as a keepsake. The main pin is inscribed with "DARWIN" and "1938," while the anchor charm has the number "38". This double pin and connecting chain are in excellent condition.
