These bayonets were designed by Admiral John Dahlgren as a replacement for the sword pattern bayonets. The Dahlgren Bowie was designed for use in close quarters combat during boarding actions, as a utility knife on-board, and as a bayonet. The blade was originally 12 inches long (now 11 5/8 inches) and is marked "USN/D.R/1864" and "anchor/P/G G" on the right ricasso and "AMES MFG CO/CHICOPEE/MASS" on the left. The brass hilt has a "DR" cartouche on the butt. Includes a leather scabbard with brass fittings.

Fine with the forward blade cut back, polished, and not sharpened, some minor pitting and light scratches, deep aged patina on the brass hilt and scabbard fittings, minor wear on the grip, and some creases in the leather.
