Simeon North was one of the most influential arms makers of the early republic beginning with manufacturing the first U.S. martial pistol, the North & Cheney Model 1799, and finally ending with the Model 1843 Hall carbines right up to his death in 1852. He was influential in developing the first milling machines and establishing truly interchangeable parts on U.S. martial arms. He manufactured 6,501 of these Model 1840 Hall carbines in 1840-1843. 6,001 of them were the standard Type II with the distinctive "fishtail" shaped breech lever. The vast majority of these were smoothbore, and some were later bored out to larger calibers and rifled. The example however remains .52 caliber and is rifled. A small number of 1840 production carbines, mostly the Type I variant, are known to have been rifled. Aside from the rifling, it and has standard sights and markings. A collection marking in white is on the trigger guard bow.

Fine with 60% plus of the original brown lacquer finish, dark original case colors, some mild oxidation concentrated on the buttplate, heavy oxidation on the trigger guard and tang and minor age and storage related wear. The lightly sanded, revarnished stock is very good and has faint cartouches, some minor surface flakes, light scratches and dings, and general mild wear. Mechanically excellent.
