Get gold carriage (6)
I believe the answer is:
landau
'carriage' is the definition.
(type of horse-drawn carriage)
'get gold' is the wordplay.
'get' becomes 'land' (landing is a kind of getting).
'gold' becomes 'au' (Au is the chemical symbol for gold).
'land'+'au'='LANDAU'
(Other definitions for landau that I've seen before include "An auld type of carriage" , "Four-wheeled vehicle with two folding hoods" , "Horse-drawn, folded-top carriage" , "Transport" , "A four-wheel covered carriage" .)
