How numbers are issued
The letter is the county; the digits are a sequence the county governor (later the police) allocated among the police districts within it. The number followed the OWNER, so a vehicle sold into another county was re-plated. Digit width grew with motorisation: up to 3 digits in 1913, 5 in several districts after the First World War, 6 by the 1960s.
