Someone at a Federation of Fly Fisher's conclave gave me this fly. He said his father was the pattern originator and this was a faithful replica of his father's pattern, the way it was originally tied: "the way it was supposed to be tied," he said. I'm pretty sure this is an example of the original West Virginia style Irresistable. And several people have told this is one of Joe Messinger Jr's flies. This sure is a good looking fly.
