In a quest for old pieces (8)
I believe the answer is:
antiques
'old pieces' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps you can see a link between them that I don't see?
'in a quest' is the wordplay.
'in a quest' anagrams to 'ANTIQUES'.
However, I am not sure how the anagram is indicated.
'for' is the link.
Can you help me to learn more?
(Other definitions for antiques that I've seen before include "valuable stuff" , "They have to be over a hundred years old" , "period pieces" , "Objects that have acquired value with age" , "Valuable items from an earlier period" .)
