Oh wow. What a shame. One of the last Models on my list is an M1887. :sad3:
Brad, there is a hole in the centre of the Kokarde, and a tiny hole underneath. The M1887 mount had split brads to attach it to the shell of the helmet, and a pin on the bottom to prevent it from rotating. This pin fit through the hole on the Kokarde. So the Kokarde was underneath and not meant to be removed.
