It was time for the experts to step in and Bill and the Yuki ladies put it all together. From initial contact by the person who donated the medal to me until we contacted the family was two weeks (thank you ladies). The story of Sydney and his medals is full of gaps. It was found in the possession of a chap who died last year, why he had it or how he came by it is anyone's guess. How it left the Burley family is also a mystery. None of that really matters now as I'll be returning the medal to Burley's great grandson who is a serving member of the Australian Army so I know it will be in very good hands.
The medal returned tally is now 562.
