Manufactured from 1863 to 1865, the Spencer Carbine was one of the most popular firearms used by the Union forces in the Civil War. It has a blade front sight, folding ladder rear sight graduated out to 800 yards and a saddle ring bar with ring. The top of the receiver has the Spencer address and patent marking, and the serial number is on the upper rear. It is fitted with a smooth walnut forearm and straight grip stock with a single barrel band, two script cartouches on the left side of the wrist and a sling swivel on the buttstock.
