Very nice, looks like a cross between a Goggo van and a Morris Commercial J Type, which had a similar looking split windscreen.
Commonwealth famous for fighter aircraft like Wirraway and Wacket, with big radial engines, so yet another road vehicle with strong connections with the aircraft industry and pilots. Voiisin, Heinkel, BMW Don Bennet/Fairthorpe, Dornier, Messerschmitt, and even a Bristol Blenheim one-off for driving around the factory. Many more too no doubt.
