Our Assessment: This is a nice Smith Carbine made by the American Machine Works during the Civil War. The Smith Carbine was unique in that it broke apart in the middle for loading and used rubber cartridges that sealed the gases in the breech, which helped to give it good accuracy compared to some of the other breechloading rifles of the era. The downside was that the rubber cartridges were hard to remove from the chamber after firing. The carbines were built by three different companies. The distributor’s name was Poultney and Trimble, which was stamped on the left side of the receiver and sometimes mistaken for the maker. Over 30,000 of these carbines were built, and were issued to at least 10 Union Cavalry regiments. This example has lost most of its exterior finish and shows wear in the stocks which could be considered light for a rifle issued in the Civil War. There is still case color showing on the interior of the breech assembly and the bore is in shockingly good condition. The barrel lockup is solid. Despite being one of the more common breech-loading carbines issued in the war, we don’t see too many Smiths come through for auction. This is sure to find a spot in a collection of Civil War martial arms. Please see our photos and good luck!
