I have previous experienced similar delay with no answers to email. But in the end I got my order within a month or so.
I am pretty sure you will get your stuff from Ironclad eventually. From my experience they are honest traders, but sometimes a bit slow to send and at answering emails.

I think it is bad buisness to not answer emails. But unfortunately I think it happens more and more often that people don't answer emails when they are delayed, which annoys me to no end. I can accept delays when I get answer to my emails, but when an order/trade is made and nothing arrives and there is no answer to emails, that just pisses me off.
Notice that above should not be seen as an attack on Ironclad miniatures, just my general view on delays and lack of contact.
