Last week I put up this post about re-coloring old doubles: Restore it or wreck it? Thoughts on making old guns look new again…
This week I realized something: A lot of folks may not know what color-case hardening or how old-school gunmakers did it (and do it). Fortunately there this video: A.A.Brown & Sons Processes – Colour Case Hardening (same as what you see above).
To learn more about what color-case hardening does and why gunmakers do it, read this article: Colour-case hardening: the last word in form.
