As an aside here… is there an active 502 Sqn association anywhere that may have further information available?

No there isn’t an active one for 502 Sqdn but there was one for 58 Sqdn which was always on the same aerodrome. If the chap that ran it is still with us.

As to the pictures, the one that pictures Ron Pierce; I had the pleasure of meeting with him back in 2001. Though sadly he too has passed away. If thats the same man I belive he completed his tour and went to become an instructor.
I do have more information but unfortinatly its all packed away ready for a house move, so unable to access it at the moment!
