Only 143 Model 1875s were manufactured at the Springfield Armory under a Congressional appropriation of $10,000 for testing. These rifles were designed by James Paris Lee, one of the great weapons designers of the late 19th century, based upon a modified Martini/Peabody action. Pulling the centrally mounted hammer back locks and cocks the action. When the hammer is pushed forward, the breechblock drops to eject the fired cartridge and allow for reloading. Once the extractor is pushed forward by the cartridge, the breech can close and the hammer can be recocked for another shot. Lee was able to fire 30 rounds in 45 seconds. These rifles use primarily Springfield trapdoor components for sights, lugs, buttplate, etc. The upper tang is marked "U.S/PAT. MAR.16.1875." Springfield Master Armorer Erskine Allin's "ESA" cartouche is on the left side of the stock. There is a F.W. Roebling III collection tag on the trigger guard. Includes a "US" marked socket bayonet with steel sheath and "US" hanger marked "CO/H/55".

Very fine, retains 85% plus original blue finish with the balance a mottled grey/brown patina. The wood is also very fine with some scattered minor to moderate dings and dents. Mechanically excellent. The bayonet is fine and the scabbard is good.
