The medal is bronze, round and bears the MFO emblem on the front, with the words ‘United in Service for Peace’ on the reverse.
The father, Bryan, served in the Brittish forces before coming to Australia on exercise, loved the place (well why wouldn't you?) and eventually transferred over and completed 42 years of service in the end. Two of the medals are English. The first medal is the General Service Medal and says "FOR CAMPAIGN SERVICE" with Clasps for Malaysia and Cyprus. Unfortunately I cannot identify the other medal, maybe one of you can. It would be nice to tell Bryan's wife exactly what they are.
The other two are Australian and you will probably recognise the Defence Force Service Medal but the other one is very special. What I have been able to find out about it is that from 1902 to 1975 the Australian Meritorious Service Medal was initially awarded to (Australian) Army non-commissioned and warrant officers who had served for at least 24 years. What is particularly special about this particular medal is that it was the last one ever struck in Australia and ever given out. Bryan's wife said there was a big fuss and it was on television and presented by a Brigadier at 4 Field Artillery Regt in Townsville.
