OK Doug

You made me go down into the bunker to pull out some Colt made pistols.
The stainless steel is a series 80 Gold Cup National Match and the blue is a non-original, non restored 1918 US Army 1911. The 1918 came with the extra slide and barrel of the same vintage.
Also seen is the 5 inch large Gambler, which I think might be a nice option for this build.
