This Austin J4 10/12cwt Light Delivery Van from 1961 belongs to Norman Wood and is currently restored. Here you can find some pictures of the van in it's new shape.
The rear part of this Austin J4 has exactly the same body pressings as the Leyland/Sherpa van. These pressings are also to be found on a type of 1989's Spanish van, presumably through the sale of the body machine tools - more information would be welcomed.
Like all BMC/Austin/Austin-Morris/BLMC and BL vehicles they shared a lot of common parts particularly with the Austin Cambridge/Morris Oxford
