Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 14, 252.
Works numbers were 9709 in December 1888; 9724 in January 1889; 9834, 9837, 9840-9841 in February; 9845, 9857 in March.
This Argentine broad-gauge bought several batches of Moguls from Dubs & Company in the late '80s, but Baldwin managed to snag an order for this octet.
