"1851 44 Caliber Navy"
To come up with the 1860 Army, Colt use the 1851 Navy frame and cut a step in it on the water table, then they made the front part of the cylinder slightly larger in diameter to accept a .44. So they are basically the same gun. This picture shows the step in the cylinder and the larger diameter of the cylinder out the front.
