This carbine was manufactured by American Machine Works of Springfield, Massachusetts circa 1863 and has a military blue barrel with a wide bass front sight with nickel-silver blade and a folding leaf rear sight. The barrel latch, trigger guard and screws are niter blued. The barrel band, receiver, hammer and buttplate have a color casehardened finish. The stock and forearm are oil-finished American walnut. The left side of the receiver is roll-stamped: "MANUFACTURED BY/AM'N M'CH'N. WKS./SPRINGFIELD MASS" in three lines above the sling bar and "ADDRESS/POULTNEY &TRIMBLE/BALTIMORE U.S.A." in three lines below it. SMITH'S PATENT/JUNE 23 1857" is roll-stamped in two vertical lines on the left side of the receiver. The serial number, "6440", is stamped on the breech lug and receiver. The left side of the stock wrist is stamped with a three-letter script inspection mark enclosed in a rectangle and the script initials "JH" enclosed in an oval. The Ordnance sub-inspection mark "JH" is stamped in block letters on the left barrel flat. Single letter Ordnance sub-inspection marks are stamped on some components. The Ordnance Department purchased 30,362 Smith Carbines during the Civil War. These carbines were widely issued to the Federal cavalry who considered the Smith Carbine to be a reliable and effective weapon.

Very fine. The carbine appears to be un-fired and retains 85% plus of the original finish. The barrel has nearly 90% of the dull military blue finish. The case colors on the barrel band, hammer and buttplate have aged to a plum brown patina but the case colors on the receiver and breech are bright. The barrel latch and trigger guard have 85% of the fire blue finish. The stock and forearm are both in very fine overall condition with a few very minor storage marks. The Ordnance inspection marks on the left side of the stock wrist are light but legible. This is an excellent, un-issued example of an important Federal Civil War carbine.
