In a letter to Edgar B. Caldwell, Nash mentions that the serial number of the lost Bo Whoop was 31108. However, a search of the Fox factory records for that serial number shows it was a 30-inch A-Grade shipped to Supplee Biddle Hardware Co. in Philadelphia, July 16, 1926, definately not a ten pound Super-Fox!! The original Bo Whoop had a straight grip, no safety, and the name Nash Buckingham engraved on the left barrel. There has never been any mention of its engraving, and none of the old pictures are close enough to really tell anything about the engraving or how much it had.
