Peter Skofic comes up with a nice set of three unidentified cars: "These are three photos of the cars which long time ago belonged to the familly von Windischgraetz (possibly the aristocratic family Windisch-Graetz?), who lived in a small town named Gonobitz located in north-eastern part of Slovenia (its today's name is Slovenske Konjice). The letter "J" on the number plate of the first car indicates "Krain", i.e. one of the regions of Austro-Hungarian empire which nowadays lies in Slovenia as well. Can anybody of the Prewar car readers identify Car Nr. 1, Car nr. 2 or Car nr.3 or possibly all three cars?"
