Yes indeed, John - although strictly speaking it shouldn't be referred to as such, and some folk are known to get quite tetchy when it is called a Matador 6x6! :mad:
It's real identity is 0854 whereas the 4x4 is a 0853, and it uses the double drive bogie from an AEC Marshall.
But to heck with the purists - as far as I'm concerned it will always be a Matador 6x6 :-D
Forgot to add - 6x6 were mainly aircraft refueling tankers, but a few were vans (mobile oxygen plant) and also carriers for Coles mobile cranes (solid beam bogie, no springs).
