An improved model designed by Erskine S. Allin, Master Armorer at Springfield Armory, to correct multiple problems encountered with the Model 1865 conversion rifles. Approximately 25,000 Civil War era muzzle loading rifle-muskets were converted at Springfield Armory to Allin's Model 1866 breech loading system and rechambered to .50-70 CF. The Model 1866 received its baptism by fire in the hands of U.S. troops in the Hayfield Fight and Wagon Box Fight, both a day apart on the 1st and 2nd of August 1867 along the Bozeman Trail, in which the severely outnumbered U.S. troops successfully held off several hundred Native American warriors. This example is dated "1865" on the lock and "1866" on the breech block. The left stock flat is marked with three faint cartouches. "GDM" (George D. Moller) collection initials marked at the toe of the stock. Includes a US socket bayonet, period leather sling, and wood tampion. Provenance: The George Moller Collection

Fine, showing mostly bright grey patina on the barrel, buttplate, and bands, with the breech block and lock retaining 85% plus of the original dark oil quenched and vibrant casehardened finishes. The wood is very good with some minor dings and scratches scattered throughout and a few hairline cracks. The included bayonet is fine, sling is very good. Mechanically excellent.
