Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 60, pp. 146. Works number was 54920 in July 1921.
Anderson Meyer & Company also bought this saddle tank about a year after it had procured the little four-coupled saddle tank for this Nantung mill. Comparison of the data shows that this locomotive had only five more square feet (0.45 sq m) of heating surface area. Although this engine's boiler was longer, it had fewer tubes of slightly larger diameter. On the other hand, the saddle tank held five times as much water as did the 1920 locomotive.
