Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 63, p 227. Works number was 54026 in November 1920.
Saddle tanks on plantations were by no means an unusual sight and this Hawaiian planter was satisfied enough with Baldwin's 1907 six-coupled radial tank (Locobase 13156) to order a second engine, but abbreviated the design by eliminating an axle.
