African Brass Staff Scepter Wand for comment

[Clubs & Arrows]

Hello. I picked up this heavy 50" brass piece recently and was wondering if any member might recognize the patterns or the odd coiled top, and could possibly help guide me in the right direction as to a tribal origin/use. The patination looked good to me, but my base of knowledge of ethnography lies in the South Pacific, so I just kind of gambled on this one because it was an interesting piece. Any help would be appreciated.

Best,
Joe
