Outfitter produces end piece with gold (6)
I believe the answer is:
tailor
'outfitter' is the definition.
(I've seen this before)
'end piece with gold' is the wordplay.
'end piece' becomes 'tail' (tail is a kind of piece. I am not sure about the 'end' bit.).
'with' is a charade indicator (letters next to each other).
'gold' becomes 'or' ('or' is the heraldic name for gold).
'tail'+'or'='TAILOR'
'produces' is the link.
Can you help me to learn more?
(Other definitions for tailor that I've seen before include "Maker of men's suits" , "Maker of garments" , "Maker of clothes, men's mostly" , "One who makes garments" , "Maker of clothes for men" .)
