The left of the receiver is marked “UNITED STATES PROPERTY” at the top, the top-front is marked “P” to the left of the sighting plane, the right-front is marked “U.S.” over a flaming bomb. The front face of the trigger assembly at the rear of the loading port is marked with the serial number, behind this is “U / S / 3”. The bottom-rear of the grip and the front of the belly are marked “U.S.”, flaming bomb and “P”.

Choke: Cylinder Bore

Sights / Optics: There is a brass bead at the front of the bayonet mount/handguard assembly. The barrel is NOT drilled for a bead.

Stock Configuration & Condition: The stocks are two piece wood with grooved slide handle, pistol grip, straight comb, serrated black hard rubber buttplate and a sling plate inlet to a scoop in the belly (the other swivel is mounted to the bayonet lug). The stocks have a few scattered light nicks, dings and scuffs. There are no chips or cracks. The LOP measures 13 7/8″ from the front of the trigger to the back of the buttplate. The plate has scattered light wear, most at the heel and toe. Overall, the stocks are in about Very Good-Fine condition.

Type of Finish: Parkerized

Finish Originality: Refinished

Bore Condition: The bore is semi-bright. There is some light erosion in the bore with more moderate erosion in the chamber.

Overall Condition: This shotgun retains about 97% of its current metal finish. There are a few scattered minor marks through the finish and light operational wear on the bolt, action bar and magazine tube. There are scattered patches of light surface erosion under the finish, most notable on the right receiver flat. The screw heads range from sharp to disfigured with useable slots, one of the bayonet lug mounting screws has had an additional slot cut. The markings are clear. Overall, this shotgun is in about Very Good-plus condition as refinished.

Mechanics: The action functions correctly. We have not fired this shotgun. As with all used firearms, a thorough cleaning may be necessary to meet your maintenance standards.

Box, Paperwork & Accessories: The installed green canvas sling is included. The sling shows scattered light wear.

Our Assessment: John Browning filed a patent for a “hammerless” shotgun with a unique take-down barrel and locking breech block on 10 Jul 1903, it was approved on 7 Feb 1905 and along with a separate 27 Aug 1907 patent, that applied to the connection between the slide arm and the fore end, became what would be the Stevens Model 520 shotgun. The same design would also be used for brand-name guns made for Western Field and Sears and would slowly be developed and improved for the next few decades with the model 620 introducing a more modern rounded receiver shape. When the United States entered WWII, Stevens was one of the manufacturers called upon to produce arms for the military, and many of the 520/620 shotguns would be used for aerial gunnery training, recreation, guards and MPs. This appears to be a commercial model 620 which has been converted to trench-gun configuration with a 20″ Cylinder Bore barrel equipped with a combination bayonet lug/heat shield, a parkerized finish, and has had US Property, proof and Ordnance marks applied to the metal and wood. This would make a nice addition to a combat shotgun collection as a placeholder until you can find a real one. It probably wouldn’t do too bad as a home defense gun, especially if you put a M1917 bayonet on the lug. Please see our photos and good luck!
