I have been thinking about human auxiliaries for my Askari Legion army, since humans get recruited into the Askari Legion all the time. Fez wearing humans are not that easy to find in 28mm, but here are some.
Coppelstone Castings: AFU2 – German East Africa Co. Askaris,
Perry Miniatures: Beja Riflemen advancing
Warlord Games: Senegalese Tirailleurs Infantry Section,
Wargame Foundry: Scruffy Uniformed Askaris – DA095
