86.156.99.68
Until 1999, UK car registration numbers included up to three letters and up to three numbers. From '63 to '83 there was a single suffix (year) letter, which became a prefix from '84 to 2001. The year letter is followed by or follows the number set.
The last two letters denoted the county where the car was first registered, hence
A(irelevant) DU(Coventry) X(single digit, irrelevant) B(1964)

Whereas registration numbers are supposed to be exclusive to an individual car and the property of the State, the Triumph factory behaved as if they owned them and the same numbers appeared on various cars from time to time. Not a great surprise when competition cars are totally rebuilt between seasons, or even races! This has caused a lot of confusion as to the actual origin of some historic cars!
