Duesenberg (~ 1920)



The Indy 500 changed to single seat cars in 1923, so it would predate that. In 1920 the cars had flat radiators, so I would say 1921 or 1922. However, I can't find any pictures from those years that show a car with the offset Duesenberg badge on the radiator or with two carb velocity stacks. But things like that were changed around often. I'd call it 1921 or '22. Ettore
