This Stompa conversion incorporates a lot of different parts, the main are the Baneblade chassis instead of feet and the use of a Battlewagon as the head.

At first I wasn’t sure about this conversion, but the more I look at the more I like it. I think the head does work very well.
I can quite easily imagine lots of Ork Meks working together on the hulk of an Imperial Guard Baneblade and building up the body of the Stompa before deciding that the partly destroyed Battlewagon that the Baneblade had taken out would look great as a head!
