Whitten, of Medina, WA, finished 25th in his 3700cc. car.  Mittler, of Milwaukee, WI, finished 10th in his "Birdcage".

Two of these large-engined Aston Martin sports/racers were built, and both were campaigned in the USA after 1958's three-liter limit made them ineligible for World Manufacturer's Championship competition.  One was raced in east coast events by George Constantine, while Bob Oker campaigned the other for Joe Lubin on the west coast.

Mittler is a well-known dealer and collector who proved his courage at the 2005 Monterey Historics when he took to the course in the notoriously evil-handling Campbell Special.
