Data from Logging Locomotives 1913 (Philadelphia, Pa: Baldwin Locomotive Works, 1913), p 11 and DeGolyer, Volume 30, p. 258. Works number was 31259 in July 1907.
Based in Marion, SC, this lumber company bought a large-capacity tender that carried 1 1/4 cords of wood. Thus the most dominant visible feature on the locomotive is an enormous Radley & Hunter spark-arresting balloon stack. The Baldwin specs stressed the need for such a stack at several points. The fuel was "'green blocks' right from company's mill [,] being from 12" to 48" in length." It rode in a tender fitted with a wood rack around its top, "arranged for carrying plenty of wood."
A hidden concomitant to most logging-engine orders appears in the Baldwin specs: "Springs to be extra heavy on acc[ount] of very rough track."
