U.S. Army Model 1902 officer's service cap eagle insignia, bronze finished brass

This original U.S. Army Model 1902 (M1902) officer's service cap insignia dates from the early 20th century, specifically spanning the period from 1902 through the 1920s.

Authorized under General Order No. 81, this badge was standard issue for American commissioned officers, distinguishing them from enlisted personnel. The insignia is crafted from die-stamped brass with a bronze finish, exhibiting a dark, naturally developed patina and authentic verdigris deposits in the crevices, consistent with its age and copper-alloy composition. It features a detailed rendering of the Coat of Arms of the United States, depicting a spread-winged bald eagle with a shield on its breast.

The eagle holds an olive branch in its right talon and a bundle of 13 arrows in its left. A scroll in its beak bears the motto 'E PLURIBUS UNUM,' and above the eagle, a constellation of 13 stars is arranged in a hexagram pattern. Measuring approximately 2.12 x 2 inches, this complete example retains its integral threaded screw-post and original circular brass fastening nut, making it a well-preserved artifact of early 20th-century American military history.
