Do Old Trafford players emerge from this ancient industrial unit? (11)
I believe the answer is:
manufactory
'this ancient industrial unit?' is the definition.
(old-fashioned term for a factory)
'do old trafford players emerge from' is the wordplay.
I cannot really understand how this works, but
'do' could be 'act' (I've seen this in another clue) and 'act' is found in the answer.
'old' could be 'o' (common abbreviation eg in OE for Old English) and 'o' is present in the answer.
'from' could be 'fr' (abbreviation) and 'fr' is found within the remaining letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for manufactory that I've seen is " production line?".)
