'forgery?' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'smile smugly about troy who distributed' is the wordplay.
'smile smugly' becomes 'smirk' (I've seen this in another clue).
'about' indicates putting letters inside.
'troy' becomes 't' (abbreviation - troy is a unit of weight).
'distributed' is an anagram indicator.
't'+'who'='twho'
'twho' is an anagram of 'thwo'.
'smirk' enclosing 'thwo' is 'SMITH WORK'.
