[2] The Welsh title allowed Avoth to enter the European championships, but was forced to retire after a torn rib ligament.
Avoth's first professional bout was against London-based fighter Doyley Brown at Grosvenor House in Mayfair, an undercard to a Ken Buchanan match.
His run was broken in May when he faced future British heavyweight champion Bunny Johnson at the Midlands Sporting Club in Solihull.
This was followed by a draw against his amateur title opponent Del Phillips, before Avoth again faced a future British heavyweight champion, Danny McAlinden.
The eight-man knockout contest was scheduled for three rounds per bout and Avoth faced Manchester-based fighter Obe Hepburn in the quarter-finals.
Avoth fought once more in 1969, a loss to Central Area champion, Billy Aird, before readjusting his sights on a new challenge, the Welsh heavyweight title, held by North Walian Carl Gizzi.
He lost to Charlie White, a fighter he had faced four times previously as a professional, before he recorded a win over Terry Feeley at the National Sporting Club.
