Bread makers
I believe the answer is:
bakers
'bread makers' is the definition.
('baker' can be a synonym of 'bread maker')
This is all the clue.
(Other definitions for bakers that I've seen before include "Unlucky number of loaves?" , "This dozen is 13 (5'1)" , "9 makers" , "Bread-makers" , "This dozen is thirteen" .)
