1066 had a couple of mark ones in 1972, (TGs 536 / 568) so it may have been one of them that went to Germany that Saturday morning.
TG536 was with 242 OCU at Dishforth in 1957. I flew down to Abingdon in 536 with Jack Huntingdon on 19th November 1957 - 3 days of day/night para dropping, formation photos and air experience flights. I never did see the photos!
