Yes, you've got it.
It started out life as a Tojeiro-Buick, chassis no. TAD 1/63, but was converted to an open car with a Ford 289 V8 for Le Mans 1964 and the chassis was renumbered TAD 1/64. As you say, it was totally destroyed by Bill Stein (see the story below) and rebuilt back to the original Tojeiro-Buick, so it was very short-lived as the puzzle car, which is probably why you didn't find it easily! Below are pictures of the car as it is today, but there's also another photo of it as the open-topped Ford-engined car.
A bit of the story:
QUOTE
Ecurie Ecosse owned more than one Tojeiro but the one you are talking about was the Tojeiro-Ford. It started out as a Tojeiro-Buick Coupe and then the engine was changed to a Ford V8 and was raced by Jackie Stewart amongst others. At the meeting you talk about Ecurie Ecosse had cut the roof off the car to convert it into a Spyder and it was driven by Bill Stein a young Scot who was racing for Ecurie Ecosse at the time. I was standing on the infield when the accident happened and it was horrendous as the car literally folded up when it hit the bank. Bill was trapped for at least fifteen minutes whilst the race continued and then in order to get him out of the car the car had to be pulled apart. Bill was badly injured and though he made a good recovery he still has problems with his legs. Bill lives in Spain today but occasionally returns to Scotland to meet up with his friends.
