I managed to pick up a couple of cheap diecast Matchbox Crossleys; these were painted up for use a transport and another for a machine gun. For crew I bought some Empress Miniatures crew sets; these I've tweaked slightly, along with a couple of spare seated figures I had.
The full East Africa Force motorised force....One of the Empress crew sets is a dismounted Vickers gun; this will be used as a British machine gun section.
