Many years ago when 72 were (briefly) at Benson, I was a pipe-smoker, and so knew that locking wire made a v g substitute for pipe-cleaners, albeit non-fluffy.
The Wessex 2nd line hangar always had (almost literally) tons of the stuff - yes you guessed it.
It was ordered by weight, and someone wanted two pounds for a particular task as so scribbled "2lb" on the chit ... which was of course read by some eejit as 216 ....
... and by the way it was also now issued in kg
And so best beloved, shortly thereafter almost exactly 240 times the desired amount duly arrived!! 216 kg
