HäT's 20mm (1:72) plastic Zulu Wars British infantry, based for the Black Powder rules.
They're painted somewhat inaccurately, but that really doesn't matter for my purposes, since these particular guys are intended for one of two generic late C19th Red and Blue armies, made up of whatever figures I can lay my hands on.
HäT figures are ideal for this sort of thing, because compared with metal figures, or even with hard plastic 28mm figures, they're as cheap as chips. The Zulu Wars sets are especially good for wargaming purposes because the sprues are mercifully free of the sorts of "character" poses you tend to get in figure sets from the likes of Airfix, Italerei, or Revell, which improves their cost/benefit ratio enormously.
The only problem with them is that they're not that easy to source here in New Zealand. There's a local chap who imports them, but I keep forgetting to get his contact details, and so whenever I see him at conventions and what-not I pretty much have to just be happy with whatever he might have in stock at that moment.
