This 1933 racer designed by William L. Jamieson of Evansville, Ind., was powered by a 600hp Curtiss
D-12. The squared fuselage was faired into the rudder. It reportedly lacked stability and flew only once,
was clocked at 300mph [13141]. Jamieson was killed in air mail duty and his racer was never used.
