That is not correct Jason. Jennie's Madeira Red Sandman was a factory windowed van..... HQ to WB panelvan's were available from the factory with side windows fitted. There are also a lot of vans with aftermarket windows fitted (dealer or others) but it is quite easy to tell the difference unless the dealer supplied factory glass to their fitters.
Good luck with your search GBTB, you'll find what you are after sooner or later....
