I found another reference to the image posted on a French reenactor site with a description of the vehicle and a few images that are captioned "Photos d'époque" which means photos of the era. I studied the details of the image before and think it is period. Note the heavy wood vehicle obstacle with barbed wire, tape in X fashion on the windows to reduce damage from glass, the heavy home made wooden ladder where theya re putting up the British flag.

But then again, I can;t determine if the clothes on the folks in the back ground look period and the soldier in the front does not appear to have a weapon.
