Impwagon
You have some incorrect info for the Thruxton chicane photo Your photo shows Homewood leading Jeff Ward in the Greatham ( space frame) Imp the Mini is I am sure 1300 cc car of Phil Winter the Mini countryman is not shown of Ginger Marshall this foto is around 75/6 as I am sure in 77 John had the Davrian based Imp running
The brands foto with Terry Attoe reminds me of my dad dragging me to watch him into paddock where he threw the min through the corner akin to an escort than a fwd understeering mini i think the foto is more 73/4 ish
