This is one search where time didn't quite work in my favour.
I received the WWII War Medal awarded to 449645 Thomas Ray Bradley in March 2012. Using service records and the electoral rolls I was able to follow Bradley and his family up until 1980. One firm piece of information I did find was that he went by the name T. Ray Bradley and was a doctor.
There is a significant amount of information available about Dr Bradley on the Internet mainly to do with his research in to the treatment of cancer. He was also made an Officer of the Order of Australia in 1990. What I wasn't able to find was any contact details. Appeals to the research institutes that provide prizes in Dr Bradley's name yielded no additional information.
Yesterday I revisited this search and I immediately got a hit on Dr Bradley's name, unfortunately it was his obituary. Dr Bradley died in August 2013.
Thanks to Dr Ray Marginson, the obituary author, and Dr Juliet Flesch, I was able to contact Dr Bradley's daughter, Julie. Thanks also goes to Andrew Cairns who originally sent me the medal. This concludes the research of all the medals that Andrew has forwarded to me.
The returned medal tally is now 1402.
