Money-making facility (6)
I believe the answer is:
talent
This clue is a double definition.
'money' is the first definition.
(I've seen this before)
'facility' is the second definition.
(I've seen this in another clue)
'making' acts as a link.
(Other definitions for talent that I've seen before include "Gift - aptitude" , "Dull means claw" , "skills" , "Biblical coin" , "Attractive people" .)
