This is one of a reported 196,000 Model 31 shotguns manufactured between 1931-1949. The "PRR" date code on the left of the matching numbered barrel dates this example to June of 1946. The right side of the receiver is marked "POLICE GUN - PROPERTY OF DELAWARE STATE POLICE". Limited examples are known with similar markings addressed to different police departments and having an 18 1/2 inch barrel length, as Remington offered them this way. "3 M" stamped on the bottom of the grip area, and a checkered steel buttplate. 2 3/4" chamber, choke constriction measures .008 inches (improved cylinder), and 13 3/4" LOP.

Excellent, retains 90% plus original blue finish with some cycling wear on the magazine tube, some light scratches concentrated on the barrel, and a few small areas of minor surface freckling. Stock is very fine with scattered dents and scratches, and distinct edges. Mechanically excellent.
