Included in this lot is a Springfield Model 1870 U.S. Navy Rifle. As with the Model 1870 Rolling Block U.S. Navy Rifle, Springfield Armory manufactured these guns c. 1871-1872 under a royalty agreement with the Remington Arms Co.; in fact, these two arms closely resemble one another. Remington's simple but effective rolling block action was considered to be the strongest of its day and was capable of handling any ammunition then available. To load a rolling block firearm, the hammer is cocked, then the breechblock is rolled backward and downward by light finger pressure, ejecting the spent cartridge. A fresh cartridge could then be loaded, and the breech closed by rolling the breechblock up and forward. Later versions locked the hammer at full-cock, but these featured a "locking action," with the hammer at half-cock when the breechblock was closed. This Model 1870 utilizes a 35 ¼” round barrel chambered in 50-70 U.S. Govt. The rifle shows heavy wear and significant loss to the original finish. The only legible stamping left on the firearm is over the tang where the letters “PA” are present. The metal on this firearm shows a dark gray patina with heavy pitting and a dark original straight grain walnut wood stock. The firearm is fit with a metal crescent butt plate and original factory swivels. Also present on the rifle is a graduated rear sight and fixed front sight. No Serial Number. This firearm qualifies as an Antique, and does not require FFL Transfer or NICS Background Check.
