One wearing gloves turns over private bank (8)
I believe the answer is:
pugilist
'one wearing gloves' is the definition.
'turns over private bank' is the wordplay.
'turns' says the letters should be written in reverse.
'over' becomes 'up' (I've seen this in other clues**).
'private' becomes 'gi'.
'bank' becomes 'list' (referring to a ship, both can mean to tilt).
'up' back-to-front is 'pu'.
'pu'+'gi'+'list'='PUGILIST'
(Other definitions for pugilist that I've seen before include "A professional boxer" , "Fist fighter" , "Prize fighter" .)
