I remember the Securicor vans from that time. They had crash-helmets, the pioneers of safety from being robbed. Problem is, that drew attention to themselves and they got robbed still!
Clydesdale Bank! they make their own banknotes. Once it was cool to take some down to England and try and use them as an intelligence test on Bar people.
They did indeed!! You could get away with it a lot of the time down south!
That's probably the only reason we never got doinked was the lack of look at is were are carrying money type helmets and the like. Lol
