The pigments used to make up the paint would have come from the same source no matter who the user was. Dark Bronze Green is an unlikely colour even for a 1945 example though as this shade didn't appear until 1948 or even later.
BTW I was looking at the NAM's Mark II at the weekend and they seem to have painted it a nondescript colour best described as 'drab'.
dr, and this could be different from the usual field arty.
