Record old emblem (4)
I believe the answer is:
logo
'emblem' is the definition.
(I've seen this before)
'record old' is the wordplay.
'record' becomes 'log' (logging is a kind of recording).
'old' becomes 'o' (abbreviation).
'log'+'o'='LOGO'
(Other definitions for logo that I've seen before include "Company emblem or device" , "Printed symbol as organisation's emblem" , "Corporate emblem" , "A firm's sign or symbol" , "Symbolic design" .)
