RE: find of a life time!
Those cedars maybe valuable. Personally, I'd put them aside for a while and get some low priced aluminums to start out with. More then likely you'll go though a few of them quickly. I know I have and still do (especially since I would never back down from 70 yards shots).
Also I'd take the bow to a knowledgeable person and have them checked out. If they were stored properly, they should be fine.
