I am from Wisconsin and remember the martini fly. It was called the double martini and I've tied them for years, but not lately. It is a really good bluegill wet fly. The original flies came from Land O Lakes Wi. The chenille bodies can be tied in any color. The red tail is marabou. The only important color is the tail. I've made them in many body color combinations. The red tail seems important to the fish. The long black fibers in your picture were not on the originals. Use small or medium round rubber legs. Again I've used different colors. Doesn't seem to matter to the fish, but fisherman like variety. Hope this helps. Al
