This is what i read from the DH site.
Riser and Limb Materials
Riser woods are Shedua with a broad beam of Bubinga through the center, outlined with hard maple. Limbs made of Eastern Hard Maple laminations and black fiberglass, with black fiberglass overlays.
If you want to know for sure, you can go to this site, Stickbow.com's Leatherwall, and ask the man who made that bow, Larry Hatfield. Here's a post about the end of the Hatfield takedown, Larry posts in it several times. Join and send him a pm, and he can tell you what year that bow was built. I think that Simon is correct, its Shedula.
