Believe it or not, John, Ansley Fox shot for Winchester using an 1897 pump. If he did use his Fox SBT they didn't last that long, probably because they Winchester Model 12s came along. Plus I think he sold out his business before too long. I think most people used Winchesters during that time so there wasn't much of a market for the single barrel trap guns for a long time to come. Now that is just about all you see.
