Thanks guys, think "Call of Cthulhu" original story, when the authorities rounded up crazed African folk who started meeting up at bonfires in the woods around obelisk. (OG "voodoo Africans" in 28mm is the look!)
I did get some Friekorps "African Townsfolk", they are very close, but they are actually Civil War era slaves, in kinda patronizing poses: "playing banjo, soft shoe dancing, carrying large bales of....something, etc.
The OG 28s AND BRIGADE 28 "Haitian Zombies" are perfect, IF THEY were 28mm.
BTW, the Blue Moon zombies are really easy to turn into hybrids. I JUST PUT PVA/WATER TISSUE PAPER CLOAKS AND HOODS ON EM, AND THEY LOOK GREAT!
