The Pathfinders badge brings back instant memories of Thorney Island Sgts' Mess in mid 50s - Lots in evidence plus quite a few of McIndoe's 'Guinea Pigs'. Regarded in awe by we 'Sprogs' and, unsurprisingly, tended to remain separated from those of us who hadn't shared their experiences. Quite a number of them were ex-617 Sqdn and bushy moustaches were common.
