Badge, symbolic device (6)
I believe the answer is:
emblem
I believe this clue is a double definition.
'badge' is the first definition.
(I know that badge is a type of badge)
'symbolic device' is the second definition.
(I've seen this before)
(Other definitions for emblem that I've seen before include "Badge, token" , "Badge or representative device" , "Symbol, representing a country say" , "Symbolic object" , "Symbol or hallmark" .)
