"it(the term) comes from the the public school my son attends."
" 'Cheltenham Average' absolutely correct"
So are you saying then that your son is a "chav" in the modern sense of the word, ie, wears burberry, drives a ****e car, and wears bling jewellery from Argos, or his he merely "Cheltenham Average".
From Wikipedia:
".Another commonly cited false etymology derives the word from Cheltenham Ladies' College. Here, it is claimed, the term was coined from the words "Cheltenham Average" (Ch-av), used by the young women of the school to describe less desirable young men of the town [6]."

Either way, back to the thread topic,,, if OM-15 is decanted into a "juniper rig" by a GE maintainer/tool controller, then surely it doesn't matter a bit about what shape, size, colour of can it comes in.
