Another great read David. I always look closely at the dates shown on these styling prototypes and think about what was happening 'outside' when all of this top secret design work was taking place inside. On September 16 in 1968 the XT Falcon and ZB Fairlane were on sale and Harry Firth would have had his plate full preparing XT GTs for the Hardie-Ferodo 500 at Bathurst on October 6 and three more for the London to Sydney Marathon which started in late November. It's amazing how different the XA/ZF styling was at that stage compared to what was on sale at the time. Fascinating stuff as always. I look forward to each issue.
