Crushed into the paint work was a Caterpillar sticker which was a major clue.
With assistance from Neil Clydsdale (who visited us at Stars of Sandstone 2019) of the Australian Caterpillar Club, it was identified as a Caterpillar No 1 Terracer with optional front truck and was manufactured sometime between 1931 and 1941.
Caterpillar provide a brief history of this implement on their website which was also supplied without a front truck and today is available as a 1:16 model from Caterpillar for $129-99.
