The way you refer to "color cased" makes it appear that you think that was a finish option. It was not. And "color cased" was not the correct term, then or now. The term was, and is, "case hardened." Case hardening was, and is, a process of heat treating that hardened the surface of the metal rather than making it uniformly harder all the way through. The mottled, multi-color surface is simply a by-product of the case hardening process, and was not done as a desired "finish" at all.

What modern gun makers call "color case" finish is not a true case hardening process, which they don't need because their frames are hardened all the way through. Rather, it is a chemical (I believe) process that is a finish, intended to replicate the appearance of the case hardened firearms of days gone by. They have to call it "color case" because they can't honestly call it "case hardened" -- because it isn't case hardened.
