Argue deep Tory reforms will be old-fashioned still (13)
I believe the answer is:
daguerreotype
'old-fashioned still' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'argue deep tory reforms' is the wordplay.
'reforms' indicates an anagram.
'argue'+'deep'+'tory'='arguedeeptory'
'arguedeeptory' is an anagram of 'DAGUERREOTYPE'.
'will be' is the link.
Can you help me to learn more?
(Other definitions for daguerreotype that I've seen before include "Eye up to regard (anag) - old photograph" , "Early form of photograph" , "Old photo" , "Shot in past" .)
