Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 17, p. 151. Works number was 12341in October 1891.
According to a Swedish response to an inquiry in Trains and Travel (Volume 13, 1952, p. 72), this was the first American-built locomotive in Sweden. The BOJ (J for Jarnvagar) later transformed into the Ysta line, which became the Malmo-Ystad Jarnvagar.
