This is a De Dion Bouton, from about 1923? I think, and possibly a V8? This car used to be in Australia, because I remember going to the auction that it was sold at in about 2000. The body I'm fairly sure would be Australian made, as it's rare to find an imported body on a car before WWII. There were tariffs on cars with imported bodies as a way to protect local body builders. So, I'd think it's an Australian body, but don't know the builder, or if the body is original to the car, or made more recently.
