Thanks guys,
@ Bloodysword , the models serving double purposes include only Zombies. I pretty much covered everything else with other West Wind models for Strange Aeons purpose.
But I might use both collections for a future thing West Wind will be releasing later this year (will talk about it on my blog tomorrow).
Quite a few models from the Strange Aeons collection on the other hand can be used in my Legends of the Old West games as well - mainly all the civilian models - and the Pinkerton looking "agents".
