I was given my Grandfathers medals several years ago. In the box that they came in was one of his epaulettes. I know the division identification is that of the 78th Infantry Division. I have tried to identify the badge underneath id but with no success. Initially I thought it was a service of arms stripe, but have not been able to match to any that are shown online. It is a black/gold/blue stripe. Does anybody know what this represents please.
