Regarding the Wolverine article in the May 2005 issue, the catalog depicted is certainly a rare and most interesting find, since it clearly shows many details of these early and remarkable engines. The history of the company is, in fact, not as mysterious as the article suggests. The story of what became of the original Wolverine company, its sale and its removal to Connecticut, are told in Beautiful Engines, Treasures of the Internal Combustion Century. (Available from Gas Engine Magazine.) The Wolverine diesel shown in the book was the subject of a magnificent restoration by the late Larry Mahan.
