The Springfield Model 1861 rifle-musket was the primary weapon used by the Union infantry during the Civil War. This example is dated "1862" on the lock and barrel, standard "Eagle/Shield" motif and "U.S./SPRINGFIELD" markings on the lock ahead of the hammer, and two cartouches are on the left stock flat, including that of Master Armorer Erskine S. Allin. Includes a U.S. socket bayonet and leather scabbard with a half circle maker's mark "R. NECE/PHILAD." (Reuben Nece & Co. of Philadelphia) and below that a circled mark "F. A. SNIFFEN/U.S/ORD. DEPt/SUB INSPECTOR" (Frankford Arsenal inspector).
