I have two Omani general service badges with the khanjar and crossed swords behind it. One has a khanjar with a rounded end and is brass while the other has a small circle at the end and is white metal. Is there any what to know what years the two styles are from? Thanks!
Here is a link to what the second one with the circle looks like:
