Correctly named medal Lt A Rodger
A Rodger served with the 5th Bn Scottish Rifles (Cameronians) and also served with the Machine Gun Corps.
There is a wound report for him dated 3/12/1917. He was promoted from 2LT to Lieutenant on 26/8/1917 and is Gazetted 4/12/1917.
It would be an interesting project to find out how he was wounded.
With a length of modern ribbon.
