The Ball Carbine was patented by Albert Ball of Worcester, Massachusetts, in 1864, and manufactured by E. G. Lamson & Company, Windsor, Vermont.
Filling a Federal Ordnance contract, approximately 1,000 were delivered in May, 1865, after the close of the Civil War.
This seven-shot .50 caliber carbine, which was chambered for the .56-50 Spencer rimfire cartridge, operated on the same principle as the later Winchester repeating rifle.
Closing the trigger guard lever feeds a cartridge from the magazine into the chamber. As the action could only be opened when the carbine was cocked, it was now ready to fire.
The carbine has a sling bar and ring on the left side of the receiver, magazine rod on the right side of the forearm and two leaf folding rear sight graduated to 600 yards. The left side of the receiver is roll stamped "E.G. LAMSON & CO./WINDSOR. VT./U.S./BALLS PATENT./JUNE, 23, 1863./MARCH, 15, 1864."
