Well, Gerd, another lesson well learned.
I bow to your extensive knowledge of the European vehicle scene compared to mine.
I obviously did not use the proper search criteria in Google to try to match bus with express.
In my defense, I got hung up on the fact that delivery vans (lieferwagen) of all marques were often called "express" and I just did not associate the term with a bus.
In any case, thanks for the new photos and I have saved them for future reference.
