As for Whitlock, there seems to be very little information about them freely available.
My prized possession , the 'Olyslager Auto Library' 'Earthmoving Vehicles' book from 1972, features Whitlock.
In addition to the well known backhoe loaders, they started building wheel loaders after buying Merton Engineering Company in 1968.
According to the book Whitlock entered into an agreement with Fuchs, allowing Whitlock to manufacture and market in the UK and elswhere certain Fuchs products.
They definitely offered the Deutz powered Whitlock-Fuchs 50R, also later with the option of Ford or Perkins engines.
There's a photo of a DD105 Dinkum Dumper too.
If I can scan them without damaged the book i'll upload the images later.
