A long-handled brush, I hear, for a former horse-drawn vehicle (8)
I believe the answer is:
brougham
'vehicle' is the definition.
(brougham is a kind of vehicle)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for brougham that I've seen before include "Four-wheeled horse-drawn carriage" , "Old carriage" , "Horse-drawn 19 down" .)
