High-grade version of Auto-5. Produced to commemorate 50th Anniversary of Ducks Unlimited. Highly engraved. Features high-gloss bluing and fancy checkered walnut stock. Approximately 5,500 manufactured by Miroku in 1987. Auctioned by Ducks Unlimited chapters to raise money for their organization. Because of this fact, it is difficult to furnish an accurate value. Commemorative firearms must be NIB with all furnished materials to command premium collector value. We furnish what we feel is a general value.
