Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 22, p. 139. Works numbers were 17272-17273 in December 1899.
The Copper Range site reports that the 51 was retired in 1922 and sold to Harry P. Bourke, Escanaba, Mi. then later resold to Northwestern Cooperage & Lumber Co of Gladstone.
52 was soon sold to the Pittsburgh & Western as their #252 and came into the Baltimore & Ohio in class B-25 and numbered #286.
