Cliff, yes you are quite correct, Dad did wear two sets of wings until he was demobbed. When he rejoined, some time later, on a permanent commission he was told that he was not allowed to any more. So you see we have had spoilsports in the RAF/War Office/MOD for years; a bit like the Gulf War medal situation, rotten sods one and all!
I'll try and dig out a photo of the old man in his battledress.
