The woman fixing old brogue, perhaps (4)
I believe the answer is:
shoe
'brogue perhaps' is the definition.
(brogue is a kind of shoe)
'the woman fixing old' is the wordplay.
'the woman' becomes 'she' (I've seen this before).
'fixing' is an insertion indicator (inserted letters are fixed inside others).
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'she' enclosing 'o' is 'SHOE'.
(Other definitions for shoe that I've seen before include "What's worn" , "mule, perhaps?" , "Winkle-picker, for example" , "Work as a farrier" , "Card dispenser" .)
