As crazy as it sounds,I think it could be a Mercedes from the 1915-20 era? "Somewhere" put up with some other items I have a thing that you hang keys on the wall with,that has a near twin to this car on it,and it's a Mercedes,about a 1914-16? It(the keyholder)came from Germany in the '70s,a gift from a German family I knew.(Kept falling off the wall,so I put it up a few years back so it wouldn't get torn up..or tear up the floor!)
