2nd Bn sgts bi-metal glengarry, a well polished and worn example.
Dissasembled view to show unusual construction. Back star of thin guage material die-struck on the arms leaving the centre plain. Scrolls fixed by rivets the upper pair extending beyond the star. Blob of hardened glue under the top left hand scroll, this is to prevent overlay rattling around due to the oversize slots cut out of star.
