Not a whole lot of info on this one, although it appears to have been around for a while; apparently popular on B.C. stillwaters at one time. Only thing I added to the recipe I found was the wire counter rib, to protect the ostrich herl. Weight optional.

thread - Danville 6/0 black
counter rib - x-small wire silver

abdomen - acrylic yarn black
rib - ostrich herl black
