This is a very nice all original Stevens 620 Trench Gun that was manufactured during WWII. Mechanically this shotgun works great and is sure to be an excellent shooter.  This shotgun started life as a riot gun and was sent to Ogden Arsenal to be manufactured into a trench gun with bayonet adapter.  This shotgun retains the original plumb colored bayonet adapter with heat shield.  The butt plate is chipped and is missing the lower piece.  This is a great example of a wartime expedient trench gun made from a low production model.
