NSN, manufactured circa 1866–1868, chambered in .50-70 Government with a 32½” round barrel. The barrel has aged to a smooth brown/grey patina, while the bore remains good with strong, well-defined rifling. Factory markings on both the lock plate and breech are sharp and clearly legible. The stock shows expected handling impressions from age and service, but remains sound and presentable. Overall appearance is honest and well preserved for a post-Civil War conversion rifle. Action functions correctly. A classic example of the U.S. Army’s early metallic-cartridge transition rifle.
