Designed by Gilbert Smith, the production of this breech loading percussion carbine was almost entirely consumed by government contracts, with limited numbers going to the civilian market. Standard three sets of markings on the left side of the frame "MANUFACTURED BY / AM'N M'CH'N. WKS / SPRINGFIELD MASS", agents' names "ADDRESS / POULTNEY & TRIMBLE / BALTIMORE U.S.A." and "SMITH'S PATENT / JUNE 23, 1857". Dovetail front sight and folding leaf rear sight absent of yard markings. Breech loading action with barrel release latch inside the trigger guard, freeing the barrel to pivot downward. Casehardened hammer and action with smooth straight grip walnut stock with a steel buttplate.

Good. The barrel has a smooth dark patina. The barrel band, sling swivels, hammer, buttplate and frame have been cleaned, some bright. The wood is good with several small minor wood fill repairs on the stock and forearm, a moderate chip on top of the wrist at the frame and overall minor dents, dings and scratches. The markings are clear. Mechanically fine.
