Here is a video I just converted from VHS to digital and then uploaded it to Youtube for you to view. :-) This came from the collection of the late Hans Pedersen via Craig Johnson and Rick Kopec before Hans.
This is the Contra Costa Grand Prix on April 2-3, 1966.
There was a letter enclosed with this video by Lewis Downs on January 16, 1988. It reads as this:
Thought you might like this bit of genuine vintage racing. Some foot notes on the film:
1. I copied it from a 16mm original, which was soundless. This footage was originally shown on a Bay Area TV program called "Spotlight on Speed" in the mid-sixties. The race is the Contra Costa Grand Prix, April 2-3, 1966. (Fil run time: 13 minutes)
2. The start of the first race shows two Shelby GT-350's in mid-pack, for just a moment. I think one of those Shelbys might be the one currently owned by NorCal member Ron Treadway (due to heavy involvement by Hayward Ford in local racing at that time).
3. The blue Stringray - - Corvette hot shoe of the period and major Cobra nemesis -- I believe to be Herb Kaplan's of Sacramento.
4. The red Mustang/Shelby (?) seen cruising into the pits with "Hank Mederios" painted on the side was the promo car from Hayward Ford; Mederios was the "high performance" salesman. He's still around doing Ford fleet sales work.
5. The 427 Cobra (CSX 2196( in the modified race was written about in the Shelby American #50 (page 37) and is presently owned, I think, by Jamey Mazzota of Sacramento. (I'm trying to locate his address to send him a copy of this.
6. The white Mustang (#77) in the sedan race is the Shelby team car that Nor-Cal member Bill Hanlon restored and recently sold to a dentist in Missouri.
