This is a 1962 German Customs VW T1 Standard Bus.
My brother saw this Split Bus in the Speicherstadt of Hamburg, Germany in front of the German Customs Museum on June 11, 2013.
The light grey T1 Zollbus is restored, has only 35000 km run, a rear tow hook and Bosch fog lights.
The Deutsches Zollmuseum exhibits the history of German custom since 1900. From the Prototyp Automuseum it is only a kilometer distance to Deutsches Zollmuseum.
