Ok, I promise that's the last time I do a Jeff Dunham ("dot commmmmmmm") reference.
Last night I cut some brass rod, drilled some holes in three little plastic skulls and two helmets. What you see before you is the result of that work. Voila - wound counters for Nob Bikers.
We've got human skull, Space Marine helmet, Ork skull, Genestealer skull, Necron Warrior head, and the Dark Eldar Warrior helmet stickin' out the side there.
