[5] In 1934, it was announced that funds were being raised to send Stanbury to compete in the World Snooker Championship.

After competing in five further championships from 1939 to 1948, but winning only two matches, Stanbury won three successive matches all 18–17 in 1949, against Herbert Francis, Jackie Rea and Herbert Holt, before losing 13–58 to Walter Donaldson.

His final entry to the championship was in 1950, and saw him defeated 15–20 by Sidney Lee[8] Whilst the British players of the time had a background in English billiards, which was played with a delicate touch, Stanbury played snooker more like pool, with powerfully hit shots.

"[10] Stanbury was a British resident for the rest of his life after emigrating in 1935,[7] and worked as a coach at a billiard hall in London for many years.

[1] He also appeared as himself in the 1949 film It Happened in Leicester Square alongside other professional players.
