A few people have asked me about the concept art for the Stalk Tank, so I figured I'd post a quick snapshot from the Black Library artbook The Sabbat Worlds Crusade by Dan Abnett (the man, the myth, the legend). Apparently it is very difficult to pick up this book for under US$100 on the second-hand market, so if anyone knows of any other sources feel free to let us all know in the comments section.
Until then, here's the concept art. I'm switching out the stubbers for flamers and I've gone with a larger, twin-linked autocannon mount.
Pics of my work in progress Stalk Tank can be found a few posts down.
