In the 1988 (42nd)edition of Gun Digest, you will find an article titled "Military Shotguns of World War II" by Eric H. Archer. From that article, you can learn many interesting facts about your gun. I have one similar to yours, and even though it's marked "long range", I see nothing to distinguish it from a normally bored 2 3/4"chambered gun.
