Old rake even damaged covering (3,6)

'damaged covering' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'old rake even' is the wordplay.
I cannot really understand how this works, but
'old' could be 'o' (common abbreviation eg in OE for Old English) and 'o' is found in the answer.
an anagram of 'even' is 'vene' which is present in the answer.
an anagram of 'rake' is 'aker' which is within the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
