Exceptional and Rare U.S. Springfield Armory First Allin Conversion Breech-Loading Rifle This is an excellent example of a historically significant M1866 "First Model" Allin conversion breech-loading rifle. After the Civil War, the federal government was experimenting with adopting some form of breech loading rifle based on the experiences of the war. Erskine Allin was the master armorer at Springfield, and he developed this model based on utilizing the 1863 percussion rifles left over from the Civil War. This is a significant and key martial rifle as it ushered in the trapdoor rifle series and actually brought the US military solidly into the breech loading era. There were some significant differences in this rifle versus the 1863 muzzle loaders such as (1) the barrel retained the 58 cal bullet, but used rimfire cartridges (2) the rear of the barrel was milled for the distinctive trapdoor breechblock assembly, (3) the side of the receiver was modified for the ratcheting extractor assembly (only found on the first model Allin conversion) on the right side which included the large trapdoor loading lever, (4) the face of the hammer was milled off for use without the percussion caps, and (5) the barrel was fitted with a modified, two position leaf rear sight. The barrel and furniture have the standard Springfield National Armory bright finish. The hammer and lock plate have a color casehardened finish, and the breechblock has a black oil-quenched finish. The lock plate is dated "1863" behind the hammer and is marked with the eagle and shield followed by "U.S./SPRINGFIELD". The left side of the stock has the double inspector cartouche: "ESA" for Erskine Allin and "SWP" for S.W. Porter. It has the original cleaning rod and an early pattern bayonet that is still in the white. Manufacturer: Springfield Armory U.S. Model: 1866 ALLIN CONVERSION BBL: 40 inch Stock: walnut Gauge: 58 RF Finish: bright Grips: Serial Number: nsn Class: Antique Condition: Excellent overall with the original armory bright polish intact on the barrel, bands, buttplate, and trigger guard/trigger bar assembly. The breech block retains 90% of the dark black oil quenched finish just starting to thin out somewhat on the firing pin hump. The hammer retains 80% of a dark dull casehardened finish, and the lock plate retains 70% of the mottled casehardened finish. The rear sight and base on the ratcheting assembly have 80% of their original blue finish. The stock is in excellent condition with some minor handling marks and scratches in some areas. The edges of the wood are sharp, and the cartouches are very clear and distinctive. The blade of the bayonet has some surface rust on the tip and upper areas with most of the socket covered with old hard rust. A superior example of a seldom encountered first model Allin conversion.
