Re: The answer surely cannot equate with its definition without its usual accompaniment however.
Ragman - the very point of Cockney rhyming slang is to separate the components of the phrase from the rhyme to those outside of knowledge of the derivation.
As per ‘My old Dutch’ for ‘wife’ - meaningless unless you know the derivation ‘Duchess of Fife’.
Excellently clued, and not at all a cause for complaint.
