Another possible name for the Blacks is Chris Strong ... later OC 20 Sqn in Singapore and last met when running AFOps in Main Building during Gulf War I.
Sorry to hear about Les Elgey [also 20 Sqn Tengah]. He was OC C Flt when they operated a handful of Single Pioneers for FAC work. I have a photo of Les on Gemas jungle strip presenting a young fg off with his Op Tankard for the Single Pin [some lad called Pete Squire - what ever happened to him?]. Oh, and Peter Latham was the Stn Cdr at the time.
