Unknown, attested from 1959 episode of UK TV series Hancock’s Half Hour. The writers (Galton and Simpson) state that the phrase was in general use when the show was broadcast. A national TV appeal in the UK in 2006 failed to find earlier references. Originally written (1963) codswallop, spelling cod's wallop is later. (Wiktionary)
