Another lovely picture sent in by Michael Schlenger: "I recently acquired this rather unusual picture of a large phaeton from the late 1920s that appears to have broken down (see the towing rope in front of the car) and is about to be repaired (or maybe is going to be dismantled for parts...).
The number plate indicates that the vehicle once was registered somewhere in Berlin ("IA"). But it's definitively not a car from a German manufacturer.
From the overall appearance I assume it's an American car, probably with a straight six engine. Since my knowledge of US cars is rather limited, I hope that someone out there can identify the marque and the model."
