Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 66 p. 334. Works numbers were 53962-53963 in November 1920.
Purchased by the government of the State of Espiritu Santo, these two wood-burning saddle tanks served a local sugar central first constructed by the state in 1912.
