Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 14, 126. Works numbers were 9115 in March 1888, 9246 and 9248 in May.
Connelly's notes say that 19 was delivered as a 2-4-2T and later converted, but the specification indicates that it was ordered with the 2-4-4T arrangement.
By 1902, 19 and 20 had been sold to Ducktown Sulphur Copper & Iron Company, possibly renumbered to 1 and 2. DSC&I was a British company that reopened copper mines in Tennessee in the 1890s and used an "open-roasting" form of ore extraction. The method inspired an early instance (1904) of property owners suing to stop environmental damage from a lawful corporation (The plaintiffs lost, appealed and won, and lost again at the Tennessee Supreme Court level.)
Sold in 1928 to locomotive recycler Georgia Car & Locomotive, 1 was apparently sold to W C Meredith of Atlanta later that year. 2 went to Carroll Brothers.
The 21 worked for several railways in the Southeast. In September 1895, it went to the Belt Railway of Chattanooga from which it was sold in 1905 to locomotive recycler Southern Iron & Equipment. Then came a series of lumber jobs starting with SI & E's sale to Decatur Lumber in July 1905, which sold it to Scotch Lumber in 1907. Scotch disposed of the tank in January 1912 by selling it to locomotive recycler Birmingham Rail & Locomotive, which sold it to Salco Lumber in April 1913.
