Our Assessment: From R.L. Wilson’s ‘The Book of Colt Firearms’, page 359 reads “With its rugged frame and hard hitting calibers, the gun in time became a favorite with the military. Exactly 151,700 were sold to the U.S Government during the First World War. New Service production, covering the years 1898 through 1944 represents one of the longest continuous runs of any model of double action Colt firearm.” This revolver is in Fine condition with a very strong action, smooth trigger pulls and a bright bore with highly defined rifling; there are some spots to the surface, but in all, this is a very attractive revolver that is parts matching and correct. This pre-war revolver is looking pretty nice being nearly 110 years old. Please see our pictures and good luck.
