Farkiing hell, that shot back memories of a"sturdy" WRAC at Ashford who liked it up the arrse. She was referred to as Judy Mazola because of the oil she used to lube up with. Legend has it she had used the oil to make a chip butty with and, being a parsimonious sort, poured the used oil back in the bottle.Crisp & dry to be exact.
Did the job.
An most excellent piece of mod marksmanship, and it was a pleasure to receive.
Also tricky when you run out of bottery.
