Winchester Model 1873 Musket with Winchester Museum record card. The museum card describes this Winchester Model 1873 as "musket, caliber 44" and states that it was shipped from Winchester on September 18, 1903. The musket has the Third Model receiver with integral dust cover guide rail and dust cover with serrated rear edges. The 30-inch round barrel has the distinctive full-length forearm secured by three bands. The barrel has a steel block front sight that serves as a lug for a socket bayonet and military style folding leaf rear sight. Factory sling swivels are mounted on the middle barrel band and stock. The carbine style buttplate has a sliding brass trap-door and the butt trap contains a five-piece, jointed, steel cleaning rod. The upper receiver tang is factory drilled and tapped. The top of the barrel is roll-stamped: "WINCHESTER'S REPEATING ARMS. NEW HAVEN. CT./KING'S IMPROVEMENT PATENTED MARCH 29. 1866.

The serial number is roll-stamped in script numerals on the lower tang between the lever latch and lower tang screw. The barrel, magazine, barrel bands, sling swivels receiver and dust cover have a blue finish. The loading port cover is fire blue. The hammer, trigger, lever and carbine buttplate are color casehardened. The stock and forearm are oil-finished, straight grain, American walnut. This musket was probably part of the group of 700 Model 1873 Muskets in the 569,000-571,000 serial number range sold by Winchester to Nicaragua in 1903; a large number of these muskets were found in new or near new condition in Central America in and returned to the United States in the 1950s.
