Four Turbo, correct I was on 17 (
PR) Sqd with the PR7 from 1966 to disbandment, agree that 60 Sqd had a far greater priority in developing / printing & interpretation of images than we had, after 17's disbandment I then moved up the road to 14 Sqd with BI8's, then they disbanded so then I went down the road & finished my tour on 60 Sqd, got about a bit !!!!!!.
