About 4 years ago I bought a Winchester Model 23 (20ga Light Duck), over the Internet, from an Auction House in CA. It was Astronaut Wally Schirra's shotgun and consigned by his family. The auction house listed the Winchester pad, that came on the Light Duck models, as an after market pad. They also listed the chokes as Full & Full, which is how the Light Duck model (Ltd Ed of 500 - 1985) came from the factory. Apparently Wally had added a full set of screw in chokes to make the gun more versatile. When I received the gun there were chokes in both barrels and the additional / extra chokes (along with the choke wrench) were sitting in the accessory compartment.
