Marine Corps Winged Eagle Insignia Pin

This item is a metallic insignia pin, likely representing a branch of the military such as the United States Marine Corps or a similar airborne unit. The pin features a central globe or spherical element, flanked by detailed outspread wings and an anchor, characteristic of nautical and aerial military symbolism. Constructed from a dark-toned metal, possibly bronze or oxidized brass, it displays a deep, aged patina with significant dark toning that suggests mid-20th-century origins, potentially around the World War II or Korean War eras. The wings exhibit fine textural detailing representing feathers, while the central globe appears smooth and polished. In terms of condition, the metal shows signs of moderate wear along the edges and recessed areas where oxidation is most prominent. No distinct maker's marks or signatures are visible in the provided view, but the casting quality indicates mass production for military issuance. The attachment mechanism on the reverse is obscured, though it appears to be a standard screw-back or clutch-style mounting. The overall craftsmanship is functional and robust, typical of military-grade hardware designed for uniform adherence.
