When used to date Remington shotguns, where the barrel can easily be changed, make sure the barrel is original to the shotgun. For example 'BL' would be January of 1920, and 'CWW' would be April of 1950. A two or three letter code on the left side of the barrel identifies the month and year of manufacture.
