The rights relating to the revolutionary DuBonnet Dolphin prototype were sold to the Ford Motor Company in 1936. Ford worked on an aerodynamic project car using some Dolphin ideas, but added other features, including four wheel steering. The Ford was never produced, but may have qualified for some patents. The puzzle drawings appear to resemble patent drawings, and show four wheel steering. Therefore, might these be drawings for a Ford aerodynamic project car, based on DuBonnet Dolphin principles, but including four wheel steering?
