I just figure if the Wizard of Oz had a tractor, it would look something like this. It was parked outside a cafe, a few minutes from my house, as I was walking by. I spoke to the driver briefly, and he said it was from 1916. He was from Brighton and heading for a steam rally.
(That's quite a drive considering...!)
One of the great things about living in Kent is the sheer amount of strange, restored, vintage stuff you see.
