Last weekend my wife and I went to San Francisco Downtown. Close to Pier 39 I saw this old friend from WW II. I took the chance to speak with the driver. I was surprised that they are still alive, the German Federal Agency for Technical Relief or better known as THW was forced to stop using their DUKWs as they run out of spare parts and they simply were too old.
The driver soon brought light up to this. The DUKWs used here are not the original ones. There is a company in the USA, who builds a better, a more modern version to be used for tourist tours.
So maybe the DUKWs used in London will be from the same company. Anyway even in the new version they look very imressing.
