produced from 1907 until 1937 built by the James Cunningham, Son & Company of Rochester, N.Y.
The Cunningham Steam Wagon was a product of the Massachusetts Steam Wagon Company of Pittsfield, MA. This firm was established in December, 1900, with the intention of manufacturing the products that the Cunningham Engineering Company from Boston, Mass. planned to develop. Instead, they built a small steam powered truck with four wheel drive.
Production ceased at the end of 1901. There is no relationship known to the Cunningham automobile from Rochester, N.Y.
