Offered is a highly detailed U.S. military-style headgear badge featuring a large spread-wing American eagle with a striped shield at its breast, decorative foliage at the base, and an applied Irish harp positioned prominently above the eagle. The harp displays fine vertical string detailing along with a raised shamrock motif, giving the piece a distinctive Irish-American character. The reverse shows multiple attachment points and hardware associated with the applied elements. The badge measures approximately 3 inches in height as shown beside the ruler. The metal surfaces exhibit substantial age-related patina, oxidation, verdigris, discoloration, surface wear, and areas of remaining finish, with the raised eagle, shield, harp, shamrock, feathers, and foliage retaining considerable detail. In our opinion, the construction, decorative motifs, attachment method, and overall appearance are consistent with a Civil War-era style military headgear insignia associated with Irish-American military tradition.
