Most cyanide hardening I have seen has more of a "Zebra" stripe appearance to it than this Folsom Leader but perhaps they were able to get a different effect using it.
Lots of the more modern cyanide case hardening results in the striped appearance you speak of. I don't much care for it, personally. The earlier methods using it didn't seem to result in that as often, IMO. A.H. Fox guns that were "cyanide cased" don't exhibit striping, that I have ever seen. The Fox cyanide colors have a mottled effect. The process also seldom results in the "halos" or "borders" of lighter colors as does charcoal pack case hardening. Most Fox guns encountered which have any color left are cyanide colors, as the bone charcoal process was discontinued by Fox around 1916, in the opinion of many Fox experts.
This Baker is attractive to me, as far as cyanide casing goes.
