Identification on this one is tricky, closest I found online is the B Series from 1957-1964, the heavier conventional trucks I found with a similar grill had quad stacked headlights, whereas this only has a pair of singles...possibly designer's whimsy. At any rate, it is commonly listed in Budgie catalogues as an International, and the '57-64 timeframe is about right.
This is a Budgie equivalent of Matchbox Super Kings or Corgi Majors, it is larger than the ESSO series typically compared to Moko era Matchbox.
