What makes this group interesting is that the medals are an official duplicate set. They are marked with a (D) and are lazer engraved rather than impressed as the originals would have been. As well as the standard WWII group, there is an Australian Service Medal 45-75 which I know was issued to Hadler in 2007. I suspect that at some point Hadler has lost his original medals and applied for a duplicate set and as a result the ASM 45-75 was also issued.
The pictures show the naming style and the duplicate D marking.
The returned medal tally is now 884.
