Have early 40s Wings cigarettes card depicting this plane.Recall reading that Seversky tried to interest the U. S. Navy in it, but despite its high performance and all-metal construction, they concluded they had no need of an amphibian with a top speed of over 275 mph.

According to Aero files http://www.aerofiles.com/_sev.html this design first flew ? June, 1933. Take notice of the wing shape.

The fabled Spitfire design flew for the first time,
5 March 1936 almost three years later. Many seem to believe the Spitfire introduced the elliptical wing.
