Spencer Model 1863 Army repeating rifle with Blakeslee 1864 Patent magazine box
Manufactured by Spencer Repeating Arms in Boston, Massachusetts c.1864, magazine box manufactured by Erasmus Blakeslee c.1864 in Chicopee, Massachusetts - serial number 5164.
.52RF Spencer 7-round tubular magazine, the wood tin and leather Blakeslee box holds 7 spare magazines for a total of 49 spare rounds of ammunition. Lever action repeater, manually cocked hammer, full length musket-style foregrip with the barrel bands and the whole shebang.
The Spencer military rifle’s success with mounted Union infantry is what prompted its better known variant, the M1860 carbine, to be adopted en masse by Union cavalry units by the end of the American Civil War.
The magazine box however was barely used, despite 30000 units being delivered to the Union during the war.
