That’s a killer collection.  Isn’t one of those BD deluxe’s an unrestored, low-mile dealer-displayed original bus with only a few hundred miles on it? (EDIT – The ’52 “Hornbecker” deluxe is unrestored with only 17k original miles on it).
What I can’t inderstand is why the Royal Mail bus isn’t amongst all those other legit VWs…seems silly that someone with that type of collection wouldn’t be all over it…especially for the asking price.
