I'm a little stuck... Click here to teach me more about this clue!

'manufacturer' is the definition.
('maker' can be a synonym of 'manufacturer')

Can you help me to learn more?

(Other definitions for maker that I've seen before include "Producer" , "Manufacturer" , "Fabricator; poet (arch.)" , "One who creates or constructs" , "Creator" .)

I've seen this clue in the Evening Standard.
