Thanks to Edwardsss for this enlightening and educational challenge. I have nothing, but wanted to throw-out some more manufacturers. I looked at all these, and some are close, but between the door hinges, "running board", swoop of the rear body, hood louver design, etc. I'm only guessing. Austro-Fiat, Austro-Tatra, Austro-Daimler, Steyr, Steyr-Daimler-Puch, Gloria, Gloriette, Mercedes, Jaguar, Rolls-Royce, Dodge (the wheels look Dodge), Graham, Ford I hope someone can help, but I've run out of time.
