Correct, but i consider the Bagnell car as an aussie based car (Ross stone looked after it???). Goudies was a "road car" group n) and the Crightion car became the petch croft "cossie" then BP francivic.
In saying that," if " the oxton car did become a cosworth, then this would be more likely done by a smaller team, and you could argue that the bagnell car could fit that catagory.

Cheers
