Whitney manufactured around 3,500 of these rifle-muskets around 1859-1862. At least 2,000 were purchased by Maryland and primarily captured by Confederate sympathizers during the Baltimore riots, and Georgia received between 1,225-1,700 of them before the outbreak of the Civil War. It has a bayonet stud/blade front sight, Whitney's long-range rear sight, "E. WHITNEY" marked lock, brass trigger guard bow, iron trigger guard strap, and boxed "SR" over "15" stamped on the left stock flat. Includes a leather sling and socket bayonet. "GDM" (George D. Moller) collection initials marked at the toe of the stock. This exact rifle-musket is pictured on pages 473 and 474 and the model is discussed on pages 472-476 in George D. Moller's "American Military Shoulder Arms, Vol. III." Provenance: The George Moller Collection
