The Sanderson Cyclone Drilling Rig was originally mounted on iron wheels and used the drilling engine to propel it. To make this rig more mobile, the owner mounted it onto a 1927 GMC "Big Brute."
While this machine could and did drill shallow oil wells, it spend most of its life drilling water wells and boring holes for coal mines.
