1,140 of these carbines were reportedly manufactured by E. Gwyn and A. C. Campbell's company, the Cosmopolitan Arms Co., for the State of Illinois and delivered in July 1862. The 5th Illinois Cavalry received over 400, and the majority were used by the 6th Illinois Cavalry during the famous Grierson's Raid that diverted Confederate attention from Grant's Vicksburg campaign. Matching serial number "322" marked on the barrel, frame, and breech block. Includes an O.B. North & Co. swivel hook.

Good overall with brown patina, freckling, light pitting, absent half of a screw head on the upper tang, and scratches, dents, chips and a non-structural crack visible on the left stock wrist. Mechanically fine.
