Thanks! It's a Colt 01911 WWI Repro in Carbonia Blue finish. It was a limited production run of 4500 made approx 15 years ago? A quite accurate repro of the originals. It's a purty sumbitch, I just kinda stumbled onto it for $900, probably worth 3x that now.
Colt also made a much larger run of them in the "Black Army" finish, but these blue ones are hard to find.
