I got some kind of expansion pack thing that says "Leaders of Smallworld, based on an entry from Michael Ormesher - UK" and seems to be added leader tokens for this game. I don't play small world, but would be willing to send this to someone if you'd like to use it. Seemed a shame to have it go to waste! Presumably you don't want to post an address here so first to post here that they want it can PM me their address and I'll pop it in the mail.
FYI, this is the thing: Small World: Leaders of Small World.
