2. NEL TARLETON
Held the British featherweight title three times, from 1931-32, 1934-36 and 1940-47, retiring undefeated as champion in 1947 when he was 41 years old. (His last fight had actually been in 1945). Remarkably, “Nella” had only one lung later in his career! Lacking a big punch but with supreme defensive skills, Tarleton twice lost to Freddie Miller in world title bids.
