1- DJB : I remember when I was younger I saw some advertisements for magazines back to seventies but what happen for this company ?
2- Ford : as it is believed this company produce construction equipment in seventies but stop .. anybody knows why ? it is sold to another company any website for that ?
3- COYOTE : I never heard about it before ,until i found it while i search ebay , but I think it is an american company and produce namely wheeled loaders , but it is also gone ?

I think:

Caterpillar bought DJB for the artic dumptruck designs.

Ford Construction division was merged with Fiat -Allis when Ford and Fiat joined forces, the construction side becoming part of Ford New Holland.

Coyote looks like a Zettlemeyer design loader.
