This unbent, excavated bridle boss, also known as a rosette, is a decorative brass device once riveted to both branches or cheeks of a Civil War era military horse bit. The boss is a 1¼" diameter circular disc with an integral upper and lower extending tang. Center portion of the boss exhibits a light checkered background behind two, ½" high, raised letters "U S". Upper tang is missing the small brass rivet but the bottom tang still holds the rivet tightly in place. A wonderful example of Federal horse equipment excavated from an undisclosed Virginia battlefield that would make a fine addition to any Civil War cavalry collection.
