PS, who remembers the one pint nylon ones you could get from NAAFI?
Not from the NAAFI, they were for overseas, I was issued with one at Insworth in 1962, when I drew my KD for Akrotiri.
Seeing I got an 'accompanied passage' and lived out for the entire tour, I started using it as a shaving mug.
And 51 years later I still do!
