The Mormon Meteor I and III were two race cars built in the 1930s by American driver Ab Jenkins.

[1] High performance parts developed for the Special, especially the "ram's horn" twin-carburetor inlet manifold, would be used on later supercharged Js (or "SJ"s as they were called by the public).

[4] Financing for the Duesenberg Special came from sponsorship solicited by Ab Jenkins from oil companies and accessory manufacturers and distributors.

Work on the car was supervised by August Duesenberg and done largely by him and by Ab Jenkins' son Marvin.

[3][5] The new owner had the car restored to its 1935 racing condition[5] and entered it in the 2007 Pebble Beach Concours d'Elegance, which it won.

The Mormon Meteor III was built in 1937 to handle the large Curtiss Conqueror airplane engine.

This intimate knowledge of the Meteor III enabled Marv to complete the meticulous restoration that required most parts to be fabricated again from scratch many years later after his father Ab's passing.
