Why me? I never heard of a pre-war 450 E... It looks too small to be a 500 K... Too big for a 170... My bet would be a 290 or 320, but I'm not even sure if the black-and-chrome grille is original. We'll need a Vorkriegsmercedes expert.
That's true, but as you know my favourites are French And Mercedes-benz is about the most opposite of French one can imagine... But thanks for your confidence, anyway
