White 850 on Heartbeat (yes, on the telly!)
So...if 621-AOK was quickly registered in 1959? when might YAB-959 have been registered?
In 1959 the Brits built about 1.2 million cars, exported about 500,000 so about 700,000 per year domestically.

The extension consisted of three-letter/three-number combinations in the range AAA1 to YYY999. Further extensions to the scheme were required in some areas by the 1950s, again due to demand depleting the pool of remaining numbers. In these areas, the format was reversed so that the number component preceded the letter component.
