Thanks Dave. The Census Number listing seems to mention just H [and Z?] 5330808-5330819 Contract S.4882 for "Tractor 4 x 4 Ant-tank 6-pdr" and "Truck 15cwt 4x4 G/S". All other "Ants" are listed as 15cwt 4x2. Unless there are more not in the listing?
Note the Michael Mouse ears' camo, which rather dates the photo.
