Product Details

**Condition:** Excellent vintage condition. Includes the original matching vintage ball-top clutch backing. Up for sale is a premium, collector-grade piece of American industrial history—an original International Harvester 10-year service milestone corporate lapel pin / tie tac. This piece features the iconic black and red enameled "IH" logo block with the "10 YEARS" banner crisp and visible along the bottom edge. * **Solid Sterling Silver:** The reverse side is explicitly hallmarked "STERLING," guaranteeing its precious metal composition. * **Balfour Maker's Mark:** Features the iconic diamond corporate logo stamp belonging to the legendary L.G. Balfour Company, famous for crafting top-tier American milestone jewelry. * **Stippled Finish:** The back features a beautiful, authentic textured/speckled finish typical of high-quality mid-century American metal casting methods (not a smooth, cheap reproduction backing).
