ed1,
Thank you for your insight and comments.You may now leave the forum if you wish.
Ray St.Ledger is one of the World's finest exponents of colour case hardening.He is used by all the British 'Best' gun manufacturers and also the Italians and Spanish.
Doug Turnbull also produces fabulous work.
Both of these companies have spent years learning and perfecting their art and craft.
The knowledge is out there available to all, if we practice, research, and consult heat treatment literature and specialist companies.
Please do not, in your ignorance,insult our intelligence with your crass and inane protestations about 'your' gunsmith's amateur efforts at falsifying a finish on guns.You are devaluing these guns please stop.
