Thank you for your replies.
Uli, thank you for the photo. Interesting car; a little over-worked or maybe as we say "over the top"... Are there more photos of that car somewhere online>
Yes, this is the Gebr. Stehling car that was in the Meilenwerk in Berlin. If you go to my blog all the way to the beginning, you will the photos there when we picked it up.
By the way, feel free to post in German since i can read it with Google Translate..
