The Mercury N-1 of 1940 was a two place all-metal monoplane featuring a unique X-spar, slotted cantilever wing with interchangeable front and rear spars. Only the one was built, NX28646, and retractable landing gear was planned for production models, of which none were built. The N-2 designation was apparently for this one, and specs were the same except for higher speeds (projected: Maximum 155 mph / Cruise 138 mph / Stall 55mph).
Production was curtailed by the war but the design reappeared in 1947 as the Midwest Mercury.
