Thanks Frank.
I would guess the Shell Tractor is the same model / probably year as this old Ringling Bros & Barnum Bailey truck, that was on display at our State Fair this year.
It is a 1926 Mack AC Bulldog. The hard rubber tires have been replaced.
I can't begin to imagine what it must have been like driving one of those in the winter... on snow... with hard rubber tires and a chain drive.
