Trying to identify this shotgun. Any suggestions on how to do so would be appreciated. No serial number or manufacturer name stamped on the barrels. Says Krupp Essen on the underside of the barrels, however, that's just the German steel used to make them. Purchased at an estate auction where no details were available. It is a 12 guage and the bore is clean with a mirror like finish. Engraving everywhere, including the screw heads. This shotgun was taken to Cabela's and two other gunshops in an effort to identify it. While they were unable to do so, they did check it out and the report from all three was that the gun was safe to fire with light loads.
