Nearest I can find is the Morris CS9, built on a 4x2 truck chassis. This had a small turret at the rear and a canvas covered section in front of that - trouble is I can't find any record of use outside the North African campaign. It may explain the Austin (Nuffield) engine though.

Here is the source of info on the Morris, about half-way down the pagehttp://www.btinternet.com/~ian.a.paterson/equiparmourarmouredcars.htm
