I shot once in a while in the mid-1970s with a young native man at the Sand Lake Club south of Anchorage who had a two barrel set Model 12 Heavy Duck with 28- and 30-inch barrels. Story was his Father had been a guide for some Winchester executives shortly after WW-II, and Winchester gave him the gun as a thank you gift.
The Winchester Special Ventilated Rib introduced in the 1954 time frame, was a Simmons Rib installed by Winchester.
