I recently acquired a set of 28" over/under barrels in 20 gauge that are marked "Marbles Game Getter, Gladstone Michigan" on the left side of the top barrel. The name of the Italian company that made it is on the right side. The vent rib is marked "FIAB. Model 1000". To me it resembles an SKB style. I am familiar with the Gamegetter short barreled handgun, but can anyone give me some information on this set of barrels. Thanks.
