1935 Hoffman?
It is a streamlined sedan with an eight-cylinder radial engine made by Roscoe C. (Rod) Hoffman around 1934 or 1935.
Hoffman was about 47 when he designed this car. He graduated from Purdue University in 1911 with a degree in mechanical engineering. He started a company called Hoffman Motor Developments in 1934 in Detroit. Hoffman was an independent engineer and knew many people in the auto industry. He may have done projects for GM. Studebaker and Packard. He became a good friend of Brooks Stevens and gifted the car to him in 1961.
The car — now dubbed the Hoffman X-8 — is believed to have evolved from a deal that the French automaker Mathis was working on with Henry Ford. Apparently Hoffman, Ford and Mathis got together to develop a radical X-engined car that was envisioned for European production. The prototype was constructed in Boston, Mass.
