Umberti model 1873 Cattleman

To give it its full title, it is the 1873 Cattleman II Brass revolver, and it is more than just a single action in an otherwise­odd­to­a­cowboy caliber. OK, the exterior first. The frame is color case­hardened. The barrel, cylinder and ejector rod housing are blued steel, and the triggerguard and grip strap are brass. This is a traditional combination and one I find quite appealing. The barrel length is 5.5 inches, what a lot of people refer to as an “Artillery” revolver.
