Patrick,
You could not come to a better place to ask because... I own the actual full-size car. This was the first of twelve BT8s built, chassis SC-64-01. The car was originally sold by the Brabham Racing Organization to Arthur Owen, then to Robs Lamplough who ran it in the North American races in 1964. He then sold it, minus the 2-liter Coventry-Climax engine, to the late Judy Kondratieff (the future wife of Howden Ganley of BRM and Tiga fame) for Bart to drive.
The car was originally red, and Judy gave it to Grizzly Engineering in NorCal to modify and fit a Cobra 289 cid engine mated to a ZF transmission. The original gearbox, a Hewland HD5, was sold to John Morton who put it in his Lotus 23.
After the terrible accident, the parts removed from the chassis for upgraded stronger parts, mostly suspension bits and front wheels, were acquired by Yours Truly with the remains of another BT8, that of Jack Brabham, chassis SC-64-07.
This was 1986. Within a few years and throwing lots of money at it, I rebuilt the Jack Brabham car and since we had lots of duplicate bits acquired from other former BT8 owners, and since I had a spare set of body parts, I built a reproduction of the Martin car back to original spec. I had acquired over time among other bits including both the original engine and gearbox, very lucky finds. There are not that many of these things around, and the numbers matched the factory records.
In 1991, I drove the first restored car at the Monterey Historic Races, sharing the car with my guest Sir Jack Brabham, here is a picture of the completed car with Yours Truly at the helm:
In the early 1990s I completed, with Judy Ganley's authorisation, the Lamplough/Martin car and raced it quite a while before parking it. Here it is at the 2000 Monterey Historic Races:
Here is a group picture of my friend Al Nowocinski, Yours Truly and his very fast LeGrand sports racer next to the resurrected BT8, SC-64-01:
For many years, I have been searching for a picture, B&W or color, of that BT8-Ford V8 at the time when Bart drove it. The car as described to me by Judy was orange with a black and white checkered stripe in the center of the body, flared rear fenders for wider wheels and a flimsy roll bar. Poor Bart did not stand a chance when he hit that concrete berm at Candlestick Park after the heim joint attaching the lower rear wishbone broke. The inquiry by the SCCA found that this had been the cause of the accident and mandated ever since, that a metal washer larger than the ball of the heim joint be fitted on the retaining bolt so that in case one would break, it would not cause such a catastrophic failure as having a wishbone loose, rendering the car with unwanted rear steering. At the time of the accident, I am told that Bart was hustling Jim Hall in his Chaparral...
One person who may have a picture or access to one is historian and friend of mine, Jerry Entin, a former Can-Am racer in a Lola T70. I will ask him and see if he can help, he appears to find stuff that no one else can find.
A few years back, I built a slot car model of my car (the other one that was Jack's personal car) for the fun of it from a very inaccurate Shark body and a Cox brass chassis and had Sir Jack sign it for me. This was published in Model Racing Journal:
Both cars were wonderful machines to drive and fast as hell. Aerodynamics were not the best and we fixed that with added appendages, so to make sure that it would be safer to drive. With such a light weight and so much power from the 2.5-liter Climax engine, those things fly. One of my favorite racing machines over the years.
