The Model 1865 First Model Allin Trapdoor design was invented by Erskine S. Allin, Master Armorer at Springfield Armory, as a solution to converting the massive surplus of, then outdated, muzzle loading rifled-muskets manufactured during the Civil War to a more modern breech loading design. Only 5,000 of these First Model Allins (also known as the Model 1865) were manufactured by altering existing rifle-muskets to the Trapdoor system in order to allow loading from the breech end with a .58 rimfire metallic cartridge. After only one year of production, Springfield shifted to manufacturing the simpler .50-70 centerfire Model 1866 Second Model Allin conversion rifles, making any surviving First Models rare and desirable. This example features an "1865" dated lock, "1864" (partial) dated barrel, boxed script "SWP" (Samuel W. Porter) and oval script "ESA" (Erskine S. Allin) inspection cartouches marked on the left stock flat, and "US" marked buttplate tang.

Rating Definition:

Very good, scattered brown patina and moderate pitting on the barrel and fittings, traces of case colors visible on the lock underneath gray patina, 70% applied black finish remains on the breech block with scattered flaking, and sharp markings in the metal. Stock is fine with defined edges, some scratches and dents, and crisp cartouches. Mechanically excellent.
