Palmer Cavalry Carbine
The Palmer Cavalry Carbine, patented in 1863 and manufactured by E.G. Lamson & Co., was a single-shot, hammer-fired bolt-action carbine chambered in .56-50 Spencer rimfire. Though 1,000 units were ordered by the Union government in 1864 and delivered in 1865, they never saw combat. Its unique bolt action features interrupted thread locking lugs, similar to the Ward-Burton rifle, and a spring-loaded ejector. The carbine includes a 3-position rear sight and a cavalry sling bar.
