In Jim Hamm and Steve Allely's book "Encyclopedia of Native American Bows, Arrows and Quivers" the Cherokee(Eastern Woodland style) bows were typically made from locust or hickory,53" to 68" long(depending whether hunting or war), 1 1/8" to 2" wide at the handle(widest point), rectangular cross section with diamond shaped string nocks or single side nocks, typically with a rawhide(squirrel or ground hog) string. These bows varied in draw weight but some of the war bows pulled 100#+.
Can you post more detailed pics? String nocks, unbraced side view and full back profile, braced and full draw.
