CMP in North Africa...

[AKosion]

Gentlemen,
First of all, thank you for the quick and comprehensive answers. To be honest, I thought the question was a long shot, but in this company, the term needs to be redefined :-) .
Bit of a faux-pas on my part mentioning aero windscreens, but I'll book an appointment for flagellation this week :-) . What I meant was that maybe the truck was designed with an open or canvas cab- I think there's a clip of such a version in Iran at britishpathe.com .
Anyway, it's a good guess the Ford used to belong to the 3rd Indian Motor Brigade, it carries what looks like their horseshoe insignia on the fender. The Brigade met the Axis in N. Africa twice, on April '41 and May '42, getting very seriously beaten by superior numbers both times. The Caunter scheme suggests the 1941 date, I think. Dating the CMP type is an extra constraint.
best regards
