 The rifle features a walnut stock with crescent buttplate and a raised cheekpiece featuring an inlaid image of four horse-heads.The First Model is distinguished by the presence of a top strap located over the cylinder, a feature absent from nearly all successive Colt revolvers until the development of the Colt Single Action Army in 1873.Although the Second Model Ring Lever rifle is identical in operation to the First Model, minor differences in appearance are apparent.
