Paired blocks I see, record price for a British sculptor (7,8)

I believe the answer is:
barbara hepworth
'paired blocks i see record price' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'british sculptor' is the wordplay.
'british' becomes 'barbara' (I can't justify this - if you can you should give a lot more credence to this answer).
'sculptor' becomes 'hepworth' (I have seen 'Modernist sculptor' mean 'hepworth' so perhaps 'sculptor' could also mean 'hepworth').
'barbara'+'hepworth'='BARBARA HEPWORTH'
'for a' is the link.
