right i am going to put my neck on the line and say the carrier is late production Mk1. when you zoom in there is no round bar on the top of the armour (or the curved tin in cases of canadian producion Mk2's) also on the drivers side rear track guard there is some luggage sat on the rations box tin tray, the two jerry cans on the left appear to be held on with the webbing straps used to hold the tarp, the tarp itself has been strapped onto the right of the battery box. the battery box (or bit i can see if it is the battery box) appears to be shorter and more central ie Mk1 rather than the elongated Mk2 style cammo net bag and storage bin.
On the rear mudguard i can see T6751- the last digit is unreadable
i await to be shot down kids
