Wargames Factory produce a range of historical, fantasy and Sci-Fi miniatures at 28mm scale.
Some of their current ranges include:
War of the Spanish Succession - the Marlburian Age.
They also have a samurai range planned, something I am very excited about:
The quality of their work isn't the best. But it is definitely improving over time. The greatcoat troops they released were of a much better quality than the zombie kit. And the samurai previews are extremely promising.
Available at Wayland Games.
