[2] Bowker began his career as an apprentice at Birmingham City, turning professional in August 1968, though he had to wait over two years for his league debut.
He found it impossible to establish himself at St Andrew's and in December 1973, after five goals in 21 league games, moved to Exeter City.
He left the Abbey Stadium in August 1977, after scoring just one goal in 17 league games, to return to Exeter City.
Once more he found a regular place in the Grecian's side, playing 102 times in the league over the next three seasons, scoring 28 goals.
In August 1980 he signed for Torquay United, where he was to play 53 league games (scoring nine goals) before joining North Devon side Bideford.
