Simon on AussieFrogs (SA) is very knowledgable on Australian delivery/manufacture details, put a post up on Renault Forum, it could well be a Heidelberg car (think they made them there?).
Are you going to restore the beasty? there are plenty of parts around but sourcing some bits is a pain, I can steer you towards some options as you go, it can be slow going though!
I originally wanted a van but they are few and far between. Worth doing properly, they're pretty cool. Is that a left hand drive btw?
