A year or so ago Doug (BuickGuy here) got in touch with me to tell of a 16 mm movie that was for sale on eBay. He and I pooled our money and bought it for this website, and I've got some copies to use as "premiums" for donations to the site. Off the top of my head I don't remember the date of the film so will have to check it out when I get through the snow and back to the house. There were only two wheels at the rear of the car, though. . . I'm pretty sure this one predates the video that Sam Hawley has posted here.
Good footage of the car, Art, Joe Petrali, and on and on. If you'd like to add this film/video to your collection of salt flats stuff all you need to do is make a donation to this site - at a minimum of $30 plus another 5 or so for USPS Priority shipping. Use the Paypal buttons on the site, and make sure you give me a mailing address to send the DVD.
PS Maybe Doug will chime in with comments about the half-hour-long film. I sent him his copy recently -- I think it'll have got to him already. Tell us about it, hey?
