Copplestone Castings has some Zanzibar regulars now available on their website.
From them to you:
AFU14 Zanzibari Regulars Marching (in a casual kind of way)
AFU15 Zanzibari Regulars in Action (by now they`ve noticed that something is going on)
The small regular army of the Sultan of Zanzibar wore white uniforms with red fezzes. If you don`t want to use them as Zanzibaris they make good all purpose askaris for a Darkest Africa campaign.
