This is a weapon from an old video showing what Halo was before it finally became what we now know as Halo: Combat Evolved. This weapon is referred to simply as the Drum Key, due to its shape. Though little information exists about it (it's present for a few seconds in the video), I decided to model it in approximately the same scale as McFarlane's Halo Reach action figures. It might also fit the Halo 3 figures. To match the color as closely as possible to the screenshots of the video, I painted the parts with a mixture of copper and yellow, creating a yellowish, mustard-y color. Then, I put a silver wash over the top. Best of luck and enjoy!
