This vehicle was created as a promotional vehicle for the Mcquay-Norris Company of St. Louis, Missouri, which manufactured replacement pistons, rings, bearings, and other automotive parts used to rebuild an engine or chassis. Six cars were built for promotional purposes but more importantly they were used as test cars. As such, they were equipped with a multitude of gauges mounted on the dash to monitor the performance of various components. The highly advanced, streamlined body design was constructed of steel and aluminum over a wood framework. The curved plexiglass windshield offers a panoramic view–except to the rear. These vehicles traveled extensively across the U.S. and Canada from 1934 to 1940. The driver sits in the middle of the body, and there is room behind the seats for a suitcase and blowby meter (used to measure how well the piston rings and valves are sealing).
