The foresight is sloted in, mostly semi-round, while the backsight is a long, V-shaped groove on the top strap above the cylinder.
The six cambered cylinder is plain in the early models, while in later ones it was fluted to achieve a small reduction in weight.
The ejector rod is mounted on a yoke (swivel) under the barrel and mostly housed in the hollow cylinder arbor, so it can be pulled out and swung to the right when needed.
In 1872, a pocket model (.442 in) with a 2.5 in barrel was produced, which was the precursor of the famous British Buldog revolvers.
