Yep, International Trophy 1974 Silverstone.
He burned his clutch on the grid and went from second to 14th (ish). By lap twenty he was on the tail of Peterson's Lotus '76 but the Swede had tyre probs. His left rear was blistering and he couldn't keep Hunt, in the Postlethwaite designed Hesketh, back.
Hunt took the lead through Woodcote which at that time was a blindingly fast right hander, and never looked back.
Those were the days.
