JB Page was Chief Cashier 1970-1980. I don't know the range of serial number prefixes yours is CZ and I have seen a HU so that kind of range suggests yours would have been issued in the early 1970's.
I would say around 1976 - I definitely recall having a real crush on a girl with the surname 'Cox' in October 1976, and getting a batch of brand new pound notes from the bank around then with the prefix 'CX', of which I kept one at the back of my wallet for months before spending it! Your note would be about the same age.
