On a tip given to me by a VA car model collector, I decided to run an internet search for this item and this is what turned up:

From "Toy Shop" May 31, 2002, Text on page "five", photo on "seven."
The item in question is a pressed steel toy Tucker by Marx, of which this is the only know prototype. According to the article, Marx was anticipating production of this toy only if and when the actual Tucker was produced in volume - you know the rest. The date affixed to its design/construction is April 10, 1947, which explains why it is a Tucker Torpedo and not a Tucker '48.
Then there was this one:

It states that since 1997, Hasbro has the option of producing action figures for the Lucas Films Indiana Jones, Willow, and Tucker (!) [exclamation in original text]. Tucker: The Man and His Dream action figures!? Though I have my reservations that they would act on this option for a film made 20 years ago, I'm never one to say never. How about a miniature Preston given chase to the local police in a Tucker Combat Car? Or a shiny new '48? Maybe a flip-over Tucker with a race-driver and a pop-out windshield? Hey, a kid can still dream at 26, right?
And on the topic of Lucas (although it pertains to an earlier posting), check out pictures of "Bail Organa's Speeder" in "Star Wars Revenge of the Sith The Visual Dictionary" by James Luceno (page 55) and "The Art of Star Wars Episode III Revenge of the Sith" by J. W. Rinzler (page 197). There is no doubt in my mind that this vehicle's "parentage" is none other than our favorite car. It was also one of the few vehicles built to full-size for the film...makes me wonder if Mr. Lucas has it parked in the garage beside its benefactor-in-design.
Best Wishes, I Look Forward to Seeing Everyone in Dulles/DC in June!
