One theory was that Ernst Roehm was BO # 1 but he never received his BO due to The night of the long knives. Hitler then took BO # 1. Wolfe Hardin owns BO # 1 along with Hitler's Brown shirt and one of his GPB's. BO # 1 is engraved rather than stamped from what I understand. I think John is correct regarding that some had more than one copy of the BO and that the spare was not numbered. Fobke had a numbered cased example and an unnumbered one attached to his uniform for example when discovered. I think there is a lot of mystery with the BO and a lot of answers we may never know.
