Thanks for that - could not see the letter in the middle - did not realise in them far flung days (I was at Valley only 5 years later!) that such a change was possible, but (as amere former pilot) glad it was. Just wondered if any of those chaps ended up as QFIs at Cranditz or Valley a few years later. (PS Anyone know what happened to a creamie QFI called John Metcalfe? He was a great instructor - well got me through!)).
