Understandably, the majority of medals we deal with are from WWI and WWII. Every so often we receive contemporary medals This one is the Australian Active Service Medal 1945-1975 awarded to Ronald Bryce Marks for service in Vietnam. Ron was a National Serviceman and he believes he lost this medal on Anzac Day.
The the returned medal tally is now 775 and this is from the NSW RSL box.
