Original M1841 "Mississippi" barrel with slots to receive a Snell Patent Saber Bayonet. These M1841 variants were made in 1855 at the Harper's Ferry Armory. Records indicate 1,646 of them were produced.
This full-length 33" barrel has been reamed smooth. The bore is clean with light pitting throughout. It is probable that the bayonet lug is a replacement due to the surface rust around it.
