Composer heading for Berlin with old sculptor (7)
I believe the answer is:
borodin
'composer' is the definition.
(Alexander Borodin was a Russian composer)
'heading for berlin with old sculptor' is the wordplay.
'heading for' indicates taking the first letters.
'with' says to put letters next to each other.
'old' becomes 'o' (abbreviation).
'sculptor' becomes 'rodin' (Auguste Rodin was a French sculptor).
The first letter of 'berlin' is 'b'.
'b'+'o'+'rodin'='BORODIN'
(Other definitions for borodin that I've seen before include "Noteworthy chap" , "Russian composer, Aleksandr Porfirevich (1834-87)" , "Russian composer (Prince Igor)" , "Prince Igor composer, d. 1887" , "Russian composer, d. 1887" .)
