Beautiful car, said to have been inspired by European sports cars of the period, perhaps Spohn Veritas cars.
Built, as you say, by Lujie Lesovsky an Emil Diedt (the latter well-known for his creations) and Phil Remington has also been mentioned as being involved, although I don't know if that was in the build process.
I'm going to have to merge this though since it's the same car as the previous puzzle..
Another picture; just because it's nice!:
