Data from Wiener (1930). Works numbers were 50272-50277 in August 1911 from Brooks and 52999-53006 in February 1913 from Schenectady
See Locobase 20094 for similar Mallets from Henschel. Compare to the Chilean State Railways engine of the same vintage (Locobase 6307) to see the same engine superheated.
