One of approximately 30,000 of these rifle-muskets manufactured by the Union Arms Company of New York City during the Civil War, and marked on the lock with the abbreviated name of Edward Robinson, one of the principals of the Union Arms Company. These muskets are believed to have been sold to the state of New York. It has the standard Model 1861 features, the eagle and shield motif over "U.S." marked at the center of the lock, "E. ROBINSON/NEW YORK" marked towards the front of the lock, "1863" dated on the tail of the lock on top of the barrel at the breech, "V/P/eagle head" proofs on the upper left barrel flat at the breech, "W.J.L.D" inspection initials marked on the left barrel flat at the breech, and "US" marked buttplate tang. Includes "US" marked socket bayonet, period leather sling, photo, and a history pamphlet of the 72nd Indiana Volunteer Infantry.

Very good with scattered brown patina on the barrel, moderate flash pitting, a mix of scattered brown and gray patina on the lock with otherwise crisp markings in the metal overall. Stock is good as sanded and re-oiled with scattered dents and scratches, a few chips in the edges of the ramrod channel and around the buttstock, a chipped/absent section to the right of the barrel tang, and a large crack running behind the lock around the wrist and partway into the left stock flat. Mechanically excellent. Included bayonet is also very good with scattered brown and gray patina, sling is fair with restitched areas, age related wear, cracking, and a torn area where it mounts to the rear sling swivel.
