Wolverine

Looking for anything relating to the Wolverine Motor Works (1894-1956) of Grand Rapids, MI and later Bridgeport, CT. They manufactured gas and diesel motors, stationary and marine, ranging in size from single to 8 cylinders. The "junior" models are relatively small, but a full size 8 cylinder is at least 10 feet tall and probably 20 feet long. I'm very interested in any advertisements, primary documents, parts, or complete motors.
