Gibson back, old china, after vole-like rodent (7)
I believe the answer is:
lemming
'rodent' is the definition.
(I know that lemming is a type of rodent)
'gibson back old china after vole-like' is the wordplay.
I cannot really see how this works, but
'china' could be 'ming' (Chinese porcelain from the Ming dynasty) and 'ming' is present in the answer.
The remaining letters 'lem' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for lemming that I've seen before include "Rodent that follows others headlong over a cliff" , "One misjudges landing" , "Rodent related to the vole" , "Northern rodent" , "Supposedly suicidal rodent" .)
