Thanks for the suggestions guys. Sorry about the blurry close-ups. I thought I had the camera on macro, but obviously not. The owner did say there had been a string handle wrap that was falling off.
Pat, thanks for the pointer to the paleoplanet thread. It sure looks to be a very similar bow and the wood does look like ipe. Oh and that blue string was made up on the spot that day, very modern.
If any body else as info or thoughts I'd love to hear them. Ron
