Yo Geoff, cant remember how it came about....but only used to wear those cotton short sleeved greyish-biege
shirts; green coveralls....thats what happens when you deciede to repair big tanky things ;-)).
As for those [censored] "anklets" at least you could crap yourself in relative comfort.
Although I must admit I was one of the few having to wear long trews in Cyprus, hats off to the RAF for the shorts!!!! (even with long socks)
