Hi Rick: Coincidentally, you should see the post below "The Man Wearing the Watch Driving the Car" which includes a photo of possibly your 911 driven by Jo at what appears to be a race event, or quite possibly the movie set for "LeMans". With all the Siffert aficionados in this group, I know you'll get your answers. Please share with us when appropriate, and if you haven not already done so, buy a nice vintage Heuer and join our group as a regular.
Best regards...Bob Keller
