Following a flood of requests. Well, OK - one request from Al at 20th Century Wargames (http://20thcenturywargames.blogspot.com/) , I dug out the box marked 'British 1940 Corps Assets'. This contains some artillery, AA, transport and command stands, together with most of a Tank Brigade (Matilda I & II), and Armoured Brigade (A9, A13, MkVI) and a Recce (armoured car) Regiment.
From the latter unit we have this Morris Armoured Car. I should point out that many of the vehicles in this box fell victim to a varnish disaster, when the spray varnish produced lots of white spots. Some models needed a full or partial repaint, but others including the Morris were treated to a heavy drybrush to conceal the worst of the damage. This scruffy look seems to suit the Morris well.
This is an old (early 1990s) Raventhorpe metal kit, made up of around ten parts. The crewman is from a Matchbox Humber - I expect he is scanning the wargames table for information, rather than targets for his Boys antitank rifle!
The square on the back of the car is a small magnetic strip for the Megablitz strength point marker. This vehicle was built and based in pre-Megablitz days.
