The MiD would always be mounted on a GSM or (among the older gentry) the 1945 Victory medal.
You mean the 1939-45 War Medal.
My own preference would be for the retrospective issue of the last commemorative medal to carry the appropriate leaf symbol. In civilian circles these have often been allocated as a poor man’s MBE. ACM Bryant wears the Golden Jubilee 2002 medal and, if my suggestion works, could simply transfer the emblem to its ribbon.
What if the recipient did not qualify for a commemorative medal ?
I think that you are on a loser.
