I assume this is nothing to do with the Bugatti-Dodge because information on it was a little sparse. There was however a T57 which was the last Bugatti to race under its own power in the 1957 Australian GP - entered by David Van Dal.
On to a website describing this car as currently having the original TT body, but having previously been shortened and having had a different body, when owned by said Mr Dal. Is this the car?
