While filling a small history of each make + links to related makes, I realize that the British automotive industry is a so worse mess than what I thought So many companies buying each other in the 20th century, that's unbelievable.
I already updated many of the BMC/Leyland, I have the Chrysler / Rootes to do after.

I created a new make for the Canadian company: https://www.imcdb.org/vehicles.php?make=DUX-Machinery
