NACA information for Hughes H-4 Hercules airfoils?

Hello, I am searching for information, particularly diagrams of the root and tip airfoils used on the Hughes H-4 Hercules, the "Spruce Goose." These are Naca 63 (420) 321 and Naca 65 (420) 415, respectively. Does anyone know where I can obtain this information, or possibly get diagrams? Thanks.
