Here is a quote from Ed Good: "most, but not all, turn out to be a fair reproduction of what i consider to be the original factory coloring". Ed Good, I challenge you to put a picture on here of an original gun that has color hardening similar to the
the ones that that I have seen done by "Master gunsmith Ed Lander". I have been collecting double guns and rifles for over 40 years and have never encountered original color hardening like Lander's. I have done color hardening before in a laboratory condition and helped Don Menck of Color Case Company
develop his color hardening methods. I would not touch one of Ed Lander's color jobs on a bet. These old guns have enough potential problems with nonmetallic inclusions let alone having preferential heat treating done to them.
