Get prepared for publication of Model Scenery (7)
I believe the answer is:
typeset
'get prepared for publication' is the definition.
(as in typesetting something for print)
'model scenery' is the wordplay.
'model' becomes 'type' (both can mean a variety or kind).
'scenery' becomes 'set' (a stage set).
'type'+'set'='TYPESET'
'of' acts as a link.
(Other definitions for typeset that I've seen before include "Prepare (text) for printing" , "(Of fonts) ready to print" , "compositor" , "Like" , "characters lined up ready for a run-off?" .)
