Archibald won the NYSAC version of the then vacant world crown when he defeated Mike Belloise on October 17, 1938. He gained universal recognition as the champion when he defeated Leo Rodak in April 1939. Archibald lost the title to Harry Jeffra in May 1940, but regained it from Jeffra on May 12, 1941. His reign was short lived as Chalky Wright knocked him out on September 11, 1941 to wrest the crown from him.
Archibald, despite his fine effort against Jeffra to regain the title, appeared to be a fighter in decline from 1939 on. In fact, Archibald lost 27 out of 34 fights from July 1939 until his retirement from the ring in August 1943. His final record was 61 wins (30 KOs), 42 losses and 5 draws.
