Exhibit part of production? (9)

I believe the answer is:
showpiece
'exhibit part of production?' is the definition.
'showpiece' can be an answer for 'exhibit' (I have seen 'Impressive exhibit ' mean 'showpiece' so perhaps 'exhibit' could also mean 'showpiece'). I'm not certain of the 'part of production?' bit.
'exhibit part' is the wordplay.
'exhibit' becomes 'show' (synonyms).
'part' becomes 'piece' (synonyms).
'show'+'piece'='SHOWPIECE'
Can you help me to learn more?
(Other definitions for showpiece that I've seen before include "Outstanding item" , "good example" , "shining example" , "Item of work presented for display" , "main feature" .)
