The first two pictures show Leverton cabs (Leverton's were Cat dealers in the UK until they were taken
over by Finning) these were known as "soft" cabs, the other two pictures show Caterpillar rops cabs.

Shovel man

thanks for that shovel man were the machines underneath the same ? I wonder did Leverton make the 3pl for the UK Cat machines ? It seems to be very hard find any information on Cat agg crawlers in the UK or perhaps Im just not looking in the right spots

The Leverton cab in the pic's was called a Westlode Cab, (Built in Westlode Street Works) Leverton worked hard at selling tractors to Farmers in Ag' spec' with near all Farmers after these tractors in the U.K. dealing with Leverton, Komatsu had a good go at getting into this market also, with Ag, spec' tractors upto 155 size with a small depot near Redditch Worc' but struggled against the like of Leverton who Farmers rated highly.
