Just a pic-update post.
It's a Soviet steam-powered magically-controlled mech that can shoot and ax. Basically.
Can I just say that Privateer Press plastics (or maybe just this batch) was super low quality. I tried plastic glue, super glue, even Bostick All-Purpose and it wouldn't stay together. This specimen is held together by cocktail-stick pinning and green stuff. See how the right arm sticks out more? That's what that is. I've given the second Warjack a fairy liquid water bath to see if that's what was required, but I've never come across miniature plastic that a tube of Polycement couldn't bond before. That Warjack is a fair bit further along by this point, now that I think of it...
Right, got to try for job tomorrow (today, oops). Happy snake-eyes!
