.52 caliber smoothbore. 21" barrel secured by two flat barrel bands. NSN. Originally browned and color casehardened finish, iron mountings, smooth walnut stock. Single shot percussion breechloading carbine with tilting breech action opened by a "fish tail" lever, designed for ramrod bayonet with a 8.5" saddle bar with ring, offset notch rear sight, offset front sight blade and sling ring in toe of triggerguard tang. Breech markings are weak and read "U.S / S. NORTH / MIDLTN / CONN / 1840" in five lines, with the second and third lines almost illegible due to wear. A block "JCB" inspection is present at the left of the breech, the mark of sub-inspector Joseph C Bragg. No cartouches are visible. Missing the ramrod bayonet.

A total of 6,501 Model 1840 Hall Carbines were made by North circa 1840-1843, with the first 500 being of the "elbow" opening lever type and the remainder using the "fish tail" lever. Many were produced with a fixed sling ring on the reverse wrist, instead of with the saddle bar, making the saddle bar variant somewhat scarce.

Good. Bore moderately oxidized with scattered light pitting. Metal with no finish remaining, having a medium pewter patina with some oxidized staining, old discoloration from old dried oil and some small areas of minor surface roughness. Buttplate heavily oxidized with moderate pitting. Markings are partially legible in the metal, none visible in wood. Mechanically functional action. The ramrod bayonet and its catch are missing. Wood wth the usual "Hall crack" behind the breech area, sanded and showing some added finish. Otherwise wood with scattered bumps, dings and mars.
