Some 1960s ex-Potteries pin-up (6)
I believe the answer is:
sexpot
'pin-up' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I can't see?
'some 1960s ex-potteries' is the wordplay.
'some p960s' becomes 's'.
'potteries' becomes 'pot' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
's'+'ex'+'pot'='SEXPOT'
Can you help me to learn more?
(Other definitions for sexpot that I've seen before include "Babe" , "Sensually attractive person" , "Tempting dish" , "Desirable" , "eg Craig? Lopez?" .)
