Approximately 1,000 of these unique two shot rifle-muskets were manufactured by J.P. Lindsay of New York between 1863-1864, according to "Flayderman's Guide" (9th Edition, 9A-342). They are known to have been tested by or issued to the 5th, 16th, and 23rd Michigan and 9th New Hampshire. The 9th tested "the new double-shooting rifles" on November 8th, 1864 and found that they "...showed off their demerits to good advantage, flashed, fizzled, and failed famously; enough to secure their condemnation and a speedy exchange to the Springfield rifle." However, it appears the 16th Michigan carried the rifles for at least a short time during the Petersburg campaign. Features two hammers for use with a superposed load, a blade front sight doubling as a bayonet lug, and three-leaf rear sight. "LINDSAY/PATENT'D.OCT.9.1860" marked on top of the breech, two oval script "ADK" (Andrew D. King) inspection cartouches stamped on the left stock flat, and "US" marked buttplate.

Exceptionally fine, exhibits armory bright iron surfaces with some scattered minor surface freckling and sharp markings. Stock is very fine with attractive original raised grain and rich oil finish, a few scattered light dents and handling marks, distinct edges and exceptionally crisp cartouches. Mechanically excellent.
