Landscapist's revolver (6)
I believe the answer is:
turner
This clue might be a double definition.
'landscapist's' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'revolver' is the second definition.
(something which turns or revolves)
Can you help me to learn more?
(Other definitions for turner that I've seen before include "English artist - lathe" , "Award in honour of great English painter" , "J. M. W. -, English eighteenth to nineteenth century painter" , "Lathe worker; a water-colourist" , "Fighting Temeraire artist" .)
