To save design time, the NYP was loosely based on the company's 1926 Ryan M-2 mailplane with the main difference being the 4,000 mile range of the NYP, and as a non-standard design the Government assigned it the registration number N-X-211 (for "experimental"). Hall documented his design in "Engineering Data on the Spirit of St. Louis" which he prepared for the National Advisory Committee for Aeronautics (NACA) and is included as an appendix to Lindbergh's 1953 Pulitzer Prize winning book, The Spirit of St. Louis.
