Duplicate parcel I made up (7)
I believe the answer is:
replica
'duplicate' is the definition.
(I've seen this before)
'parcel i made up' is the wordplay.
'made up' indicates anagramming the letters.
'parcel'+'i'='parceli'
'parceli' anagrammed gives 'REPLICA'.
(Other definitions for replica that I've seen before include "Reproduction, fascsimile" , "Parcel I found with exact copy" , "Copy original" , "I parcel (anag) - reproduction" , "Reproduction, exact copy" .)
