Get gold on the carriage (6)
I believe the answer is:
landau
'the carriage' is the definition.
(type of horse-drawn carriage)
'get gold on' is the wordplay.
'get' becomes 'land' (landing is a kind of getting).
'gold' becomes 'au' (Au is the chemical symbol for gold).
'on' says to put letters next to each other.
'land'+'au'='LANDAU'
(Other definitions for landau that I've seen before include "Horse-drawn, folded-top carriage" , "Horse-drawn carriage or car with folding top" , "A four-wheel covered carriage" , "An auld type of carriage" , "Transport" .)
