Approximately 1,000 of these unique two shot rifle-muskets were manufactured by J.P. Lindsay of New York between 1863-1864. 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. "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.

Very fine, retaining armory bright metal surfaces with some patches of dark colored light pitting visible mostly on the hammers and buttplate, and some minor marring on some of the screw heads. Stock is also very fine with attractive original raised grains and rich oil finish, a few scattered light scratches and handling marks, sharp edges and crisp cartouches. Mechanically excellent.
