That's a Zandonella LJ36 made (?) by an obscure manfacturer from Melbourne/AUS.
@Arunas: I certainly know how you've found it. Unfortunately no trace leads to DHoffmann's #50! This car (#50) is an fully functional car with Swiss number plate and they still wait in Australia for government's permission? Designed by someone called "Wyatt Turner" who hardly can make a straight line?
Sorry, but that must be a bad joke!
