Question for Air Force Hq

I am trying to get a photo of an ex Air Force member of the old GSU at Thornhill MT Section. He served in the 60's and 70's but was killed around 1977 and buried in Gwelo with full Military Honours. He was WO II Elliot Vuchirayi. I do not have his service number. Can you pse assist? I suspect the olly photos of him would be in his original personal file, a copy of which would be at HQ.
