    the chemical they were dipping the frames in would have likely been potassium cyanide, followed by a water quench. Stevens used the same process and there were a few others who did as well. There are many ways to case harden steel and the process does not always yield colors. It takes a special technique and the right materials to acheive good results.

    Here's the 1969 Uberti M1860 Army next to the Signature Colt Dragoon showing the size comparison and a bit of the color casehardening.

    Here are some parts I color case hardened. Parts to a Stevens Visible loader.
    I brought these polished clean parts up to 1800 degrees in a sealed stainless crucible, packed with bone charcoal and small strips of leather. I let it heat soak for about 4 hours then knocked the bottom off the crucible and let the entire contenets drop into a laundry sink full of cold water with air bubble agitation.

    ^ Nice colors.

    My Hermann Weihrauch made EAA Big Bore Bounty Hunter has very nice case colors, as do my Uberti 1862 Police and my Pietta 1851 Navy.

    My Pedersoli Howdah pistol, however has largely faded into a flat gray.

    I wonder which processes Weihrauch and Pedersoli use?
