Thanks for the point. I could find only one reference to this car on the whole of the 'net. This was a page concerning the original Nota which was being sold by a well-known Australian auction house, and one of the comments appended mentioned this car. It was a pure guess on my part, but an educated one, because the Neuens car I posted earlier in this thread was also Simca-engined, and the puzzle car had what looked like production car wheels.
I don't know how you find these puzzles!
PS whilst investigating this puzzle, I noticed that the Australian Simca owners' club is called Simca Swallow, and this seems to be what they call the Vedette model.
