"BK" January 1941 date code on the left breech area of the matching numbered barrel. This Remington Model 31 is one of a reported 8,992 total delivered on U.S. government contract between 1940-1944 in both riot and training configurations, per page 91 of "Combat Shotguns" (2007) by Bruce Canfield. Most of the early U.S. government acquired Model 31 shotguns were of the commercial type and used for security duties and gunnery training. 2 3/4 inch chamber and improved cylinder choke. The solid matte rib is fitted with dual bead sights. With standard commercial markings on the barrel and frame, as well as "RLB" and flaming bomb U.S. inspection marks on the left side of the frame. Neither the barrel nor the frame features any other U.S. property markings. The stock and forearm are oil finished black walnut with checkering on the pistol grip and bottom portions of the forearm. The buttstock has a plastic Remington buttplate and pistol grip cap. Length of pull is 14 inches.

Excellent plus, as issued overall with 98% bright original blue finish remaining, some slide retraction marks visible on the magazine tube and action bar, and scattered light handling marks. The excellent wood has almost all of the original oil finish, sharp checkering, and just a few small scattered dings. Mechanically excellent. One will not find a finer example!
