Looks like a Old Commer bus or Commer van like the one used in Mad Max 2 as the Main Gate at the Compound
Austin is writ upon the front.
I drove a Commer delivery van in the early 60's, and the Commer doesn't have such a "hip" line. Commer vans have a finer grille as well. Very similar to the one in the pic though.
I am half-heartedly on the lookout for a Commer actually. If one comes my way for the right price. But - like everything, they have gone through the roof price wise.
