Thanks for the contact Hanno. Kuno made contact via the AEC Society forum so I've had a chance to search for a photo of what I *think* the desert wreck is.
The model type is 1966 "AEC Militant 0860 6x6" and these three were supplied to Sudan. The cabs look just the same as the one in the Libyan desert, don't you think?
Maybe the back end of the desert chassis has been cut off.
I am always very interested in any photos of AECs.
