Data from Catalogue Descriptive of Simple and Compound Locomotives built by Brooks Locomotive Works, Dunkirk, NY (Buffalo, NY: Matthew-Northrup Company, 1899).
Works number was 2952.
It's hard to believe that this is a standard-gauge engine, but the catalogue insists on it. This pint-size Mogul served in Minnesota, first for Itasca Lumber and later for the mystically named Minneapolis & Rainy River RR (which was nicknamed the Gut and Liver Route -- so much for mysticism).
