"I don't have the box but the cylinder is hot blue and the rest of the gun is charcoal blue. I want the cylinder to be charcoal blue."
Interesting, I wonder how that happened? If the cylinder does need to be charcoal blued, Turnbull is the obvious choice. Turnbull did the armory bluing on USFA's until USFA installed their own bluing furnace. From what I was told, Turnbull is also the one who installed the furnace and taught USFA how to do it. Ron's Gunshop also does charcoal bluing, he did the Colt 1911 WWI repro's. Classic Guns L.T.D also does it; I'm not sure of any others.
