This is an excellent example of a WWII U.S. Army contract Stevens Model 520-30 trench shotgun with the correct bayonet lug adapter and ventilated handguard. The right side of the barrel has the three line address along with "P/Ordnance Bomb" at the breech with the three line Stevens Company address. The left side has the two line gauge markings of: "PROOF TESTED-12 GAUGE/-2 3/4 INCH CHAMBER-". Choke gauges at cylinder. The left side of the receiver is stamped "MOD. 520-30", and it has the correct "P" proof on top of the barrel and front edge of the receiver. The lower right side also has the correct "P/Ordnance Bomb" proof. It has an all blue finish with smooth forearm and pistol grip stock with a black plastic buttplate. The stock and bayonet lug are correctly fitted with sling swivels, and it comes with a green canvas GI sling. Length of pull is 14 inches.

Excellent with 98% plus of the original blue finish overall showing only minor edge and high spot wear. The stock and pump handle are both in excellent condition showing only minor handling marks. Mechanically excellent. An exceptionally high condition Stevens Trench Shotgun.
