Josh, believe it is a york, lemonwood longbow. They made lots like this one with a fiber backing. The small hole in the upper limb nock is a string keeper. It came with a piece of elastic string tied to the upper string loop and then run up and through the small hole, knotted on the backside. This would keep the string from getting out of adjustment if it were a flemish string. Also it aided in keeping the string from being pulled off, while removing the bow from a bowcase.Jerry Hill..................
