I used to have the picture.
This is all you could see of the machine.
It was a motorway construction.
The story goes that locals told them not to go through the area.
There was also a picture of a mass of concrete piles (pillars) hundreds, where the road was going, to support the carriageway.
It was like one of these that they lost.
That's why they have a glazed panel in the roof of the cab - escape route.
