It was the number 509 A/GMS Sundance GoldCstRdsts, Harold Motsenbocker entry. It ran 164.213 on a 215.000 record. I found another picture of the car and posted it in the post above where the old pic was.
For a short video of the 509 car in ...uhhhhh...action click
here and then click on "2 Spins".
I also follow the Thacker and Shine F/BSR efforts. They were in England a while back in a wind tunnel and found several things that worked and didn't work to make a '29 Ford slicker. They must have had some issues because they ran 26 mph slower than the 186.861 mph record.
Here's a C3 that is still in the photos section.
Here's the Thacker and Shine roadster.
I love this Ardun powered old spring car.
