Squire Francis Waterman (27 July 1923 – 8 October 2019) , better known as Split Waterman, was an English speedway rider who twice finished second in the Speedway World Championship final. Waterman took up speedway while serving in the British Army in Italy and went on to become one of the top riders of the post-war era. He made the headlines again in the late 1960s when he was convicted of gold smuggling and firearms offences.https://en.wikipedia.org/wiki/Split_Waterman
The wiki version is toned down, but the more detailed one is in the Times behind a paywall but here's a sample.
On a visit from Spain for the annual dinner-dance of the Veteran (now World) Speedway Riders’ Association in Coventry in 2002, The Guardian found Waterman “second in the toasts only to the Queen” and noted that “his charisma at 79, in tinted aviators and royal-blue cummerbund, was still enough to send multitudes of septuagenarians sprinting to the top table, autograph books in hand”. His racing prowess was not the only topic of conversation. “I smuggled gold! I smuggled guns! Zambia, Rhodesia, the jungle,” he declared.
Waterman reflected that when his speedway career faded, so did his prospects of escaping the attention of the police. “The people who worked at Wembley were ex-Old Bill,” he said in a book, Speedway: The Greatest Moments. “And that’s how I used to get out of trouble. What sort of trouble? You name it, I’ve done it.”
Split Waterman, speedway racer and smuggler, was born on July 27, 1923. He died on October 8, 2019, aged 96
