These old Colts had a great history. Created by John Browning and favored by Clyde Bowers Colt made a lot of these. Many were used and U.S. officers pistols. This one is odd. I am going to try to research it. Has a dull matt finish on it and there is a A in a diamond stamped on the frame. Indicates it was a WWI gun shipped to Belgium. Nice grips and a two tone Colt magazine.
