Thanks Gandolf,
The body is made slender by simply stroking and pinching the feather fibers forward. Yes, the split tail is achieved by cutting the center of the extended part of the feather away.
It is certainly an old style pattern. I will try to post a pic of the fly from above and I think it will become more clear.
Top view. I notice that I should have brought the fibers in tighter to make a "skinnier" body.
