The lock plate is dated "1863" behind the hammer with the standard U.S./Colt markings stamped ahead of the hammer. The bolster has the eagle/shield motif. The barrel is also dated "1863" and has "V/P/eagle head proofs" and "F STEEL". Equipped with a three leaf rear sight graduated to 500 yards. Full length stock with three "U" stamped barrel bands, "US" marked buttplate and two script cartouches on the left flat. The iron ramrod has a trumpet hade. The socket bayonet is marked "US".

Very fine as issued. The musket has a mixture of a mottled bright appearance and a smooth dark brown patina. The stock is excellent with a series of small shallow gouges behind the rear barrel band and some very scattered minor handling marks. The cartouches are excellent. Mechanically excellent. This totally original and untocuhed Colt musket appears to have come right out of an attic!
