We dropped in to have a look at the Roger May Machinery Museum in Pinjarra when we were down that way camping recently.
This is a Two Ton Caterpillar Holt Tractor build in the pre-1930's and overhauled in 1993 by Westrac in Bunbury and further restored by the Museum this year.
Caterpillar was started in California in the late 1880's by Benjamin Holt and Daniel Best.
None of this information I knew prior to reading the plaque on the vehicle at the Museum.
