Dan Strohl of Hemmings Blog kindly indentified this formidable machine as the Golden Eagle aka Thunderbowl Comet. Although the car's story varies from one teller to the next, it did at least portray a Muroc Dry Lake LSR contender in a Jimmy Stewart B-movie called Speed in 1936, turning up years later as opening act at the Carpenteria Thunderbowl, a quarter-mile dirt track near Santa Barbara, California. As Auto Puzzler editor Ray B. posted, "The Carpinteria Thunderbowl was operational between 1947 and 1956. Anton Krivanek reminisced about the circuit: "I used to go there when I was about 14. The guy who owned it had a great big streamliner called the "Thunderbowl Comet". It had the name painted on the side and it had a big fin on the back end with a stylized comet with a tail of sparks and stars painted on it. He'd trundle it around the track before the races to impress the rubes (me). In my memory it was so long it could hardly make it around the corners... Years later I saw it parked alongside Highway 14 out near Acton as a draw for a sad little western roadside attraction. I told Strother MacMinn about it and he drove out there and checked it out. Turned out it was a pseudo land speed car built for a movie in the '30s and he had seen it parked on the street in Hollyweird in the late '30s or '40s. It was on a stretched L29 Cord chassis and eventually was bought and dismantled for its Cord parts." According to Strohl, the beast is still out there.
