I know that I have seen listings for a “Bogardus Gun Club” model made by W&C Scott. Adam Bogardus did shoot Scott guns during his career and perhaps was sponsored by them hence the named model. I can’t recall seeing a “Bogardus Duck Club”, though. Looking through my new DGJ I & R I also didn’t see an article referencing such a gun but under W&C Scott there is a full column of references to DGJ articles that could be gone through. As for here, there are some “search engine masters” (I’m not one.) who could perhaps find a mention or past discussion for you. Let’s hope.
