A Call for Help from HIVIANS in Africa

I have purchased from auction several carved wooden items that were generically listed as 'African'.

In reselling them I'd like to more accurately represent the cultures they are meant to be indicative off.

Can any Hivians from the continent nudge me in the correct direction, please?

First is this pair of drummers. I have seen similar ones attributed as Yoruban (Hopefully someone from Hive Naija can help here), but also more generically (and location challenging) Kenyan, and African.

This trio of salad utensils has similar items listed as African, or even Tribal, but I've also seen them presented as Maasai

Finally, these carved wall plaques have similar listed as African or Tribal.

No one would list bagpipes as 'Traditional European Instrument' or list a wooden carving of a Greek statue as 'Native European Carving'. I like to make item locations as specific as possible, and I definitely would prefer to avoid any lazy colonial representations.

Thank you in advance for any assistance.
