Gwyn & Campbell manufactured around 8,200 of Type I and Type II carbines in 1863 and 1864 in the same factory where they had previously manufactured carbines under the Cosmopolitan Arms Co. name. They are essentially updated version of the Cosmopolitan carbines and were issued to a variety of Midwestern units during the Civil War. This one has the standard Type II markings and features. Matching serial numbers are visible on the bottom of the barrel, frame, and breechblock. Boxed script "WHR" cartouche on the left of the wrist, and small "WHR" inspector initials on the top rear of the stock. "GDM" (George D. Moller) collection initials marked at the toe of the stock. Includes wood tampion. Provenance: The George Moller Collection
