This model is my counts-as Thunderfire Cannon. It's based on the old metal Lizardmen Stegadon model, with the horns replaced by brain-implants. The turret consists of a regular, round 25mm base (with those weird hooks from the vehicle accessory sprue stuck on the side) topped with a Rhino driver's hatch. The gun itself is a cut-down twin-linked lascannon with the covering plate of the Vindicator's robot-arm (the one that holds the shell) stuck on top.
