I'm happy I picked up a some of those figures when I did, though I am still looking for a lot of them. (BTW, if anyone wants to PM me regarding a trade in the US, I've got spare figures from the spearmen regiment, especially command figures, and I am looking for some of the MM15/1 figures.)
They also did a set of imperial looking dwarves with separate handguns. The only pic I've got right now is of one I converted to hold a plastic empire greatsword:

Here's another converted old figure I thought would fit in with the imperial look, it's the champion from the 2nd version (?) of Bugmans Rangers. I think you may still be able to get him through mail order. All I did was off the axe and replaced it with a greatsword:
