The Colt Model 1839 Carbine is an early percussion revolving smoothbore carbine manufactured by the Patent Arms Manufacturing Company between 1838 and 1841. Produced alongside the Colt Second Model Ring Lever rifle (preceded by the First Model Ring Lever rifle, Samuel Colt's first manufactured firearm), the Model 1839 was the most popular longarm of the Patent Arms period. The Model 1839 Carbine is differentiated from Colt's Ring Lever rifles by the lack of a cocking ring lever and the presence of an external hammer, which, when manually cocked, would rotate the six-shot cylinder to the next position. Approximately 950 Model 1839 Carbines were manufactured, and an additional shotgun variant, the Model 1839 Shotgun, was produced from 1839 to 1841 with approximately 225 manufactured. Though
