The 38443M00001 was off a CKD chassis assembled in Melbourne Plant. The 1944 MODEL truck has a plate on it that has been mis-stamped as it should be 'X4' and not '4X'. X4 was the code for Australian delivery.

Note that there were other 00001 chassis, with each plant using their own system with a plant identifier: A, B, M, P and S.
