I had an AEC MK3 complete with sliding doors and push-out windscreen and it was a bugger for throwing flames out of the exhaust - not very good for a tanker carrying flammables

.Was sent back to the yard early one morning by Sheffield police with instructions to "get it sorted".The fitters,as always shoved some additive in the derv tank,affectionally known as "Cabdrivers Linctus" and all was well until the next time.
