The Model 1833 is very significant as the first adopted U.S. martial percussion firearm and also the first U.S. martial arm to employ an underbarrel bayonet that slides into the ramrod channel. 1,028 were manufactured in .58 caliber in 1834, and 6,135 were manufactured in .52 caliber in 1836-1839. Originally issued in smoothbore, this example has been updated with six-groove rifling at some point during it's service life and remains in .52 caliber. The Model 1833 was primarily used by the 1st and 2nd U.S. Dragoons in the Indian Wars, including the Seminole Wars in Florida, and some remained in use during the Civil War, though by then they were considered obsolete. "U.S/S. NORTH/MIDLtn/CONN/1837" (the date is faint) marked breech block. "NWP" (Nahum W. Patch) inspection initials marked on the left breech end of the barrel, and an oval script "NWP" inspection cartouche marked on the left stock flat. The implement compartment on the underside of the buttstock contains a ball puller and combination pick/screwdriver. Provenance: The George Moller Collection
