When we (North Star that is) produced miniatures for the last Silver Bayonet supplement, Egypt, we thought about doing a British and a French Unit kitted out for Egypt. We didn't have time to do it before the release, but Mike Owen did get four of the figures done. Rather than hold onto them, we made them available as part of the preorder program. They were actually really popular, we sold hundreds.
They were always going to be part of full 8 figure Units, and Mike Owen has now done the rest of the figures.
We're going to make them available, once Andrew Taylor has them all painted for the box cover, probably some time in September.
What I've done now is make the 12 new figures available to buy to those people who already have the first 4 from the Egypt preorder program. I've called them 'Top Up' packs.
