Facsimile I put on record perhaps (12)
I believe the answer is:
reproduction
'facsimile' is the definition.
(thesaurus)
'i put on record perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'i'+'put'+'on'+'record'='iputonrecord'
'iputonrecord' is an anagram of 'REPRODUCTION'.
(Other definitions for reproduction that I've seen before include "Having a family" , "Print made of a painting" , "hardly original" , "Copy of an artwork" , "Copy (of a work of art)" .)
