Some fully restore old musical instrument (4)

I believe the answer is:

lyre

'old musical instrument' is the definition.
(ancient stringed instrument)

'some fully restore' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'LYRE' is hidden within 'fully restore'.

(Other definitions for lyre that I've seen before include "Ancient Greece harp" , "Early harp" , "Ancient harp-like instrument" , "Old instrument, like a harp" , "Instrument played by Orpheus" .)

I've seen this clue in The Times.
