Wow, those are different from any Drakes I've seen. It seems that Harry was always unconventional and unafraid to try anything. A friend who met him several times told me that towards the end of his life he was on a quest to duplicate the recorded feats of the ancient Turks, and whoever else, with bows he made from the same materials and methods they used. He was the flight bow genius of his time, but could never get a flight bow that would match the feats of those ancient archers using their methods.
