Glaive/polearms supposedly from Congo

[blue lander]

These suckers arrived today. They're quite sturdy and heavily built. There's still some wood particles in the socket and the edges has some dings on them, so I guess they were actually mounted and used at some point. Nothing else really to report other than some markings on the spine which I've attached a picture of. I'd love to remount them on an appropriate pole if I knew what it was supposed to look like.
