I also don`t think, that it is original on every car - but another Hebmüller, which was offered to me and some other Hebguys a few month ago, has the same. As Christian told me as his best friend we are talking not about the same car. "My" car was delivered to Fleischauer od Cologne and is stocked in a barn for the past 35 years, so the sign must be an old assecoiry of the 1950s.
