First up there's Oddfellow's Sphere from the climactic scene of Pax Britannia: Dark Side (which, I have to say, has been going down a storm). This kit includes an incredible 8 minifigures (4 goodies and 4 baddies), including the Lego incarnation of PB competition winner Jared Shurin.
Next up there's the lunar rover Copernicus, again from Pax Britannia: Dark Side. This set contains 6 minifigures - Ulysses Quicksilver and Nimrod, in both their normal attire and environment suits, and two alien Selenites.
And then there's the Rolls Royce Mark 4 Silver Phantom, that made its first appearance in the very first PB novel Pax Britannia: Unnatural History. This set has two minifigures - the dashing dandy detective, and Hero of the Empire, Ulysses Quicksilver, and his indefatigable manservant Nimrod.
As with all good Lego kits, you can make a plethora of different models from each of the kits - or why not combine them all in one incredible Pax Britannia-gasm of steampunk-y goodness?
