The Engineer is made of Ziracote wood polished to a Scrabble-tile smoothness, the edges slightly rounded. a soldered brass tank feeds the drive through two brass pipes. A magnified service light illuminates when the drive is used. The cap has gears on both sides, with a heavy sawtooth gear on the front. Will Rockwell's etched signature and date appear on the back of the tank. The Engineer comes nestled in velvet in its own custom vintage tin box. It includes a folder called Goodies, with Will Rockwell's Steampunk desktop and a photo album of his other work.
