The Hildebrand car was built in Singen/Hohentwiel (South Germany) near the ruins of the castle Hohentwiel. That’s why the emblem shows a kneeling knight with a sword in his hands.
Not much is known about this firm but is it likely that there was a very small production. The specialist of car production numbers, Mr. Hans Lipp, suggests around 100 cars were built, and it seems that not a single car survives today.
