That's a Bob Popovics fleye. Get a copy of his book Pop Fleyes and it will give a bunch of pictures and a number of VERY VERY useful flies for fishing the mid atlantic region.
One of the tricks i have used to make the epoxy easier, since i do not have a wheel to dry them on, is to use a long shank hook and then place mylar tubing around the fly back to the curve. Saturate this with epoxy and it holds the shape very well.
