So after looking though most of the display pieces, consisting of old Sprint Cars, USAC Midgets, Indy cars, Stock Cars etc....and lots of old engines to fit those cars I see the following:



All I found about this was that it was run in a Midget. It was built by Ron Hoettels who had engines under the SESCO name I think. He was in Milwaukee, WI when he built this I am told.
Pretty cool find in a museum of race cars.
