My link at #7 would place the photo at the 1968 Farnborough display:
The first public display of the team was on May 9, 1968 at Biggin Hill Air Fair, follows by demonstrations at Brawdy, Yeovilton and Farnborough. At the end of the season the team flew coordinated displays with No. 809 Squadron display team “Phoenix Five”, which flew Buccaneers. At the end of 1968 the Simon's Sircus display team was disbanded.
From my log book that was 21/22 Sep 68 as we too did a display with the Spitfire and Hurricane. It was the same year the Atlantic crashed in to the hangar.
