Data from Roy V Wright (Ed.) 1912 Locomotive Cyclopedia of American Practice, Sixth Edition (New York: Simmons-Boardman Publishing Company, 1912), p. 157. Works numbers were 2121 in January 1900 and 3603 in August 1906.
Owned by Peter B and Robert S Bradley, the Bulow phosphate mines were located on the Rantowles Creek south of Charleston in South Carolina. (The creek emptied into the Stono River, which gained notoriety in the mid-18th Century for being the site of the first significant slave rebellion in England's North American colonies.)
This little saddle tank ran on the railroad that began on the east bank of Rantowles Creek and ran up to Bear Swamp Road.
