In addition to all of their other great 15mm miniatures, Blue Moon Manufacturing has a line of pirates. There are loads of pirates, ever utile civilians, and even some reasonably affordable resin ships.
The current powerhouse in 15mm miniatures would have to be Blue Moon Manufacturing. They have a small but evocative horror line which includes zombies (of course), but also werewolves & vampires, wolves, and a Jack the Ripper vignette featuring a famous consulting detective.
Blue Moon Manufacturing has released a much-anticipated line of 15mm figures (really 18mm these days) for exploring Deepest, Darkest Africa.
The line currently comprises 12 tribes of natives (including pygmies), askaris, porters (with ivory, nicely complementing the Irregular bearers who have crates), witchdoctors, native villagers (in camp and canoes), and even captives being cooked in a giant pot (!), along with the usual Great White Hunters, Men & Women of Adventure. I’ll leave the quintet pictured above to the imagination.
