A few comments on this photo after close inspection:
The nearside bonnet is the wrong shape and has no windscreen support on it, nor does it have any strengthening corrugations in the bonnet.The front of the bonnet on the nearside has repeat marks left to right where the bottom edge has been formed from the photoshop clone tool being set on one position and repeated. The edge of the bonnet overlaps the front grill edge by about a scale 3"  !!! 
The anti decapitation bar  looks an addition to the photo and not the vehicle.  It is, I think, a crude attempt to disguise the join between the two bonnet halves. If you look below the number plate the bar comes up just a little way in front of the bumper and then disappears.   How is the number plate fitted if the bar is in front of the bumper. 
The number plate has been added, it is a different pixel size to the remainder of the front of the Champ and you can see the sharp cut edge of the inserted piece of graphic. 
There is also a sharpness definition difference to the off side section of the anti decapitation bar just above the bonnet. this is commensurate with adding a straight line edge to that section from photoshop. 
The offside wing is again a totally cobble repetative clone with what looks like the bonnet securing hook repeated. 
There are also two very strange cloned squarish blobs in front of the Armoured car's off side front wheel just below the back of the Champs offside front wing.
I t is my surmize that for whatever reason this Champ has been inserted and made up in front of the picture of the armoured car. It is probable that the original picture of the offside of the Champ had a soldier leaning on it and he has been crudely removed and the blobs on the grond are where his feet may have been.  The windscreen is not like any Champ windscreen I have ever seen either. There is no depth between the inner frame and the  bonnet
