M_Boats: M-17 Designer

Hi, I am curious who designed the M-17. I had always been told that Lyle Hess was the designer of the Montgomery 17 Good old Boat magazine is now stating that Jerry Montgomery is claiming that he was the designer and not Lyle Hess. I have been told that the original drawings (blueprints) state that Lyle Hess is the designer of record on the M-17. Possibly both participated in the design of the Montgomery 17. Does anybody know who actually designed the Montgomery 17? Thanks very much. Kirk Hill
