Well, OK. I think Diggory was/is talking about a far-more complex device than a fork. But to a large degree, I think he's right. Almost all of the American shotgun designs (other than the Smiths and early Lefevers) are varients of the A&D (and I do hope I'm quoting him correctly here!). Certainly, most post-1890 European designs are A&Ds, unless, of course, they are sidelocks. Early-on, some of them might have paid for the use of the design, but I suspect that most did not. Certainly not after patent-protection expired.
