Pre-war to Civil War U.S. Army Officer's Regiment of Riflemen Kepi Insignia
Two officer’s M1851 pre Civil War pattern embroidered cap insignia for regiment of riflemen as worn on the officer’s kepi.
Both are in excellent condition. The badge shown first (top) is unworn, the badge shown second (bottom) has very light age and possible removed from a kepi.
These were used in William Emerson’s Encyclopedia of U.S. Army Insignia & Uniforms reference.
