Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 13, p. 186. Works number was 8376 in February 1887.
This little lumber tank was tasked with negotiating 10-degree curves and 4% grades. At some point, MC & F sold the 3 to Palmetto Phosphate. PHos had over 23,000 acres of phosphate-rock lands in north Florida.
In 1907, PPhos sold the locomotive to Green Bay Phosphate, also in Florida, where it toiled for at least 2 more decades.
