Adam Karpowicz's book, "Ottoman Turkish Bows manufacture and design" is an excellent resource for building Asiatic composite bows. Also, contact James Parker, Huntworthyproductions(a sponsor). James makes beautiful composite bows, all the way they were originally made. This past year he has been making 6 or 8 different Asiatic composite bows, each in different stages of completion. James won "Bow of the Year" on PA with one of his composites(an American Plains style composite) and had a composite win "Bow of the Month" last month.
