Excellent, retains 95% plus original blue finish overall showing only minor cycling wear, with sharp edges and markings in the metal. Wood is also excellent with defined edges, some light handling marks, and rich oil finish. Mechanically excellent. Bayonet and scabbard are both very fine. This is among the finest examples of a U.S. Stevens Model 520-30 trench shotgun we have ever offered at Rock Island Auction!
