Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 49, p 109 Works number was 34008 in November 1909.
It was the London-based Ethelburga Syndicate, Ltd that actually negotiated the sale of this small Ten-wheeler to the Nicaraguan railway.

J G White Engineering Corporation of #43 Exchange Place, New York City, ordered these oil-burning Ten-wheelers for the Pacifico to operate on the 40 lb/yard (20 kg/metre) rail, up 3% grades, and around relatively gentle 10 degree curves. (Two similar Consolidations are shown in Locobase 14192). The firebox was lined with fire brick for oil burning and Baldwin's "standard oil burning arrangement" placed the burner in the front end of the firebox.
The specs also include a common post-delivery "Hereafter" note, in this instance dated 10 May 1915, that acknowledged the stresses encountered by these small engines operating in rough circumstances: "The equalizing beam links to be made stronger."
