aZooZa, my Dad was also at Upavon in 1965 having gone from spec-rec for promotion to Wg Cdr to redundancy in the latest round of defence cuts within a matter of months. His last flying tour as an A1 instructor had been 2i/c Transport Command Examining Unit at Benson, after which he did the Russian interpreter's course at Tangmere. Long story involving air crash in Russia killing many military and air attaches meant him dipping out on a diplo tour in Moscow, so he finished his operational time as Ops O for a SIGINT Wing at Butzweilerhof near Cologne. Sadly, he departed the fix 2 years ago so am unable to find out if he knew your Dad; HQ 38 Gp did seem to be a clearing-house for people departing the service.
If chopper2004
hadn't already done so, I'd have uploaded the Arthur Gibson black-and-white pic from the Yearbook.
