The hilt design on this sword matches those of Boyle & Gable/Boyle, Gamble & MacFee of Richmond, Virginia. The only markings are "CS" among the designs on the guard and "16" on the guard to the left of the blade and the pommel by the tail end of the knuckle guard which is correct for these swords as discussed on pages 8-10 of "Confederate Edged Weapons" by William Albaugh II. Also note the star above the "C" and the ear of corn near the knuckle guard. The blade is roughly 30 3/4 inches long and has been modified to be double edged, and the tang is now secured via a square nut on the pommel. The grip has black leather and simple wire wrap. The browned iron scabbard has gilt brass fittings and is an old replacement, likely from the same period as the blade alteration.

Very good with moderate overall wear, some mild pitting, aged patina on the brass, strong brown finish on the scabbard along with mild oxidation, and play in the blade to hilt fit. Definitely an interesting Confederate officer's sword.
