I am seeking information about one of my shotguns. 16ga. SxS marked Timmer Koblenz on the rib. On the sides of the barrels marked Amtlich Rauchlos Erprobt which translates from German to Certified Smokeless Tested. Belgian proof marks on the water table, false sideplates, engraved with hunting dogs. Very high quality. I have searched the internet in vane.
