Style large or small-scale reproduction (5)
I believe the answer is:
'small-scale reproduction' is the definition.
(small replica of something)
'style large' is the wordplay.
'style' becomes 'mode' (synonyms).
'large' becomes 'L' (eg in clothes sizes).
'or' is the link.
(Other definitions for model that I've seen before include "Example to follow" , "Possibly the last" , "She saunters on the catwalk" , "Ideal example" , "Scale representation" .)
