Was out hunting with NZPoohBear yesterday and dug this up. Did a bit of a search on the internet which said:
"Mounted to the Uniforms shoulder Straps to indicate rank. The “pip” or rank indicator for Officers is based on the Star of the Military Division of the Most Honorable Order of the Bath. Three Joined as One: It refers to the union of England, Scotland and Ireland to become the United Kingdom."
I believe it is from WW2 because it has parachutes instead of crowns. Anyway, it was a nice to find something besides 1 and 2 cents once in a while.
