Nothing much to say about the first hammerer: the usual chainmail and not-so-white tabard.
For the second one, I've replaced the axe by a hammer coming from an old box of plastic warriors. And the figure on his helmet gave me the idea for a regiment name: the 'Black Boar Company'.
The third one nicely fitted with my newly found theme: the helmet crest, plus one of my precious Marauder shields.
And a second boar shield for the last one... Only 6 shields left, I'll have to choose carefully my models if I want to complete a 20 men regiment...
