I did some research on the web about Morocco c.1900 (which I think could be an interesting context for some Pulp adventures) and I found a few pictures and texts about the "Mokhaznis" - the soldiers of the "Makhzen" (Moroccan authority).
Weisgerber (a witness) writes that the caïd of Casablanca had about 30 cavalrymen; 50 gunners, whose job was to salute visiting ships with 18th century cannons; and an infantry "tabor" of theorically 200 men (but much less in reality, because officers kept some of the money).
Infantry uniform was a red fez (the Moroccan fez is shorter than others), a red vest, blue wide breeches which let the lower legs bare, and "babouches" lemon yellow.
Some were in rags; discipline appeared low to European observers (soldiers sitting on the ground as often as they could, etc); however some of these men attempted to resist the French in 1907, and the gunners fired their antique cannons against the attacking French warships!
Christian Houel (another witness) writes that in Casablanca in 1907, mokhaznis were armed with a Chassepot and a bayonet. Some times later, he describes mokhaznis of the army of Moulay Hafid (who was fighting against the French): they had Chassepot or Gras rifles, or flintlocks; some were given the same uniform, other stayed in rags; there were officers but no NCOs; the soldiers received no training.
I don't know suitable miniatures. Foundry "Belgian askaris" perhaps could do, with babouches added, but their rifle is wrong.
