Ah, but PN, can you recall the 'duties of a sentry' still?
Were you, too, forced into khaki horsehair with blanco'd belt and gaiters at school because there was no RAF section?
The Set Wireless No 38 Mk 3, Telephone F Mk 2, Set Wireless 88 etc. were my forte - bugger all that marching about stuff lugging the Lee Enfield No 4 around the parade ground!
I too have a pair of those black socks as issued in 1968. Heaven knows what they were made from though - still no holes after 38 years of use! Not that I wore them much in the last 15 or so years as they are horribly uncomfortable
