In 1967 COLT made the first of it's series of four WWI commemorative issues. 100 of each issue were hand engraved by the factory. 25 were "Special Deluxe" and 75 were "Deluxe" This is one of the 75 "Deluxe" Chateau Thierry produced and is signed RWM by the Colt engraver. You rarely see an engraved version on the market. They are highly desirable to a Colt collector. There is one in the "Buffalo Bill Cody Museum" C&R. Comes with Colt display case. As new, never fired, case has minor scuffs.
