The Production Broadcast Sheet for that van indicated side windows and it was delivered with only one side brace per side in lieu of the three provided in a windowless van. The glass inserts were delivered to the delaler with the van and installed by a local body builder. He put the stripes on also. The glass had the same markings as the rest of the glass in the van. They might still be in the shed somewhere - i'll have a look on the weekend.
