Not able to update this due to dead graphics card.
Just a quick copy paste of the Headless Bulldozer edit of the Minigun Bulldozer's texture to make him stand out a little more, so that you can identify him a little easier on some darker maps (and before he's inside the room, blasting you into oblivion).
This is just a modified version of the Headless Bulldozer's texture with the red eyes removed, and the visor changed to the Minigun Bulldozer's "Teeth" variant.
