Replacement Imperial Guard Heads

I have a buddy who is starting up an Imperial Guard army. I had a bunch of leftover undead zombies so he decided to use those bits to convert a Nurgle Imperail Guard army. He has done an amazing job so far and I hope to have some pictures of his models up soon.

A while back he showed me something really cool. He found some replacement heads that are modeled up with gas masks. They are made by Pig Iron Productions. You can purchase them from this page over at TheWarStore.com. Below is a picture that I looted off of The War Store.
