This Smith carbine was manufactured by American Machine Works in Springfield, Massachusetts, early on during the Civil War. Most of these carbines were purchased by the government and issued to cavalry units. The carbine has a blue part round, part octagon barrel with dovetail mounted brass front sight blade and folding leaf rear sight. The left side of the casehardened receiver is fitted with a sling bar and ring for a cavalry carbine sling. The stock and forearm are oil finished walnut. The Smith patent markings are stamped on the left side of the receiver under the sling bar. The three-line Poultney & Trimble address is stamped near the top, and the three-line American Machine Works address is located above the sling bar. The serial number is located on the two hinge components. The left side of the stock wrist is stamped with a "JH" cartouche. "LFR" is stamped on the left barrel flat at the breech.

Very fine. The carbine retains 85% of the original blue finish with some thinning and minor marks. The action retains 60% strong case colors along with a brown patina. The stock and forearm are also very fine with some minor scratches and a gouge on the right side. The markings, including the cartouche, are clear. The action is excellent. This carbine is in very fine condition for a Civil War era carbine especially given that this example was martially inspected and thus likely issued to a cavalryman during the war.
