MR1101 FINE SPENCER CARBINE; Caliber 50 RF. 20 inch round barrel with 3-groove rifled bore. Gun appears to have post-war arsenal alterations. Barrel lacks the 1865 markings, is not numbered and retains a good amount blue. Likely a replacement at the time of alteration. Action also retains much of an arsenal applied case color. Wood is in VG condition. Action is crisp and tight. Nice Spencer Carbine!
