Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 36, p. 316. Works numbers were 35594-35595 in November 1910 and 38220 in August 1912.
Although F Benn & Son brokered a pair of saddle tanks for two different usinas (sugar plantations), the Brazil and Hilda came off the line in consecutive order and had exactly the same dimensions. The design repeated that of the 1909 engines shown in Locobase 13150. The Guarany came along 26 months later.
