This cover page is from a U.S. Navy technical publication, "Elmer Carries On," the Pilot's and Mechanic's Operating Bulletin for the Sperry A-3 (Mk 3) Gyropilot, dated September 1944. Published under Bureau of Aeronautics designation NavAer 05-45-536, the bulletin used a cartoon mascot to help aircrew and maintenance personnel understand the operation of this early autopilot system. Its presence among later personal papers suggests it was retained as a reference document or memento. Project: 218077
