According to Dave Hughes, these have been around since the 1800's http://books.google.com/books?id=8sG...hackle&f=false This link has a great SBS and is taken from the book Trout Flies.

I usually tie them with a tail, so I guess they are more of a streamer. The body is a mixed dubbing using ice dub and pine squirrel. I have had great luck with this on our local trout streams last spring.
