Rebuilt each, partly following a model (10)
I believe the answer is:
archetypal
'following a model' is the definition.
(following an archetype)
'rebuilt each partly' is the wordplay.
'rebuilt' is an anagram indicator.
'each'+'partly'='eachpartly'
'eachpartly' anagrammed gives 'ARCHETYPAL'.
(Other definitions for archetypal that I've seen before include "Classic N chapel tray (anag)" , "Quintessential" , "Model" .)
