IIRC, shortly after I traveled through East Afrika in '95/'96 I read The Last Hero by Peter Forbath.
https://www.goodreads.com/book/show/773652.The_Last_HeroVery enjoyable, if a little embellished.
I also use the 15mm Irregular riflemen as my Zanzibaris.
The Baluchis from ERM are quite good but a bit bigger than some 15's.
I've put a picute of him at the bottom on my pics.
I took a few pictures of Bagamoyo and Zanzibar.
The pics of Bagamayo are the German Bomba and the Custom house. The third pic is of the Hotel which Emin Pasha fell off the balcony to his death.
Fourth is a pic of Zanzibar The Sultans palace is (IIRC) the Clocktower on the left and the two white triangles are the church on the former site of the slave market.
The fifth is from the inside of the fort.
The sixth is me, having just recovered from Malaria (nearly died).
This was during Ramadan, and quite sweltering. You would walk outside and suddenly realise you are soaking wet, like a bucket of sweat just tossed over us. You didn't even register getting hot.
The seventh is a comparison pic. The fellow in white is a Baluchi from ERM
