Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 30, p. 198. . Works number was 30267 in February 1907.
William C McLauchlin's Scotch Manufacturing Company of Milligan, Fla dealt in wood products.
Some time before the mid-1920s, the SMC sold the 1 to locomotive rebuilder/reseller Birmingham Rail & Locomotive. Equitable Equipment bought the 1 from BR & L in July 1925 on behalf of Swift Hunter Lumber Company of Atmore, Ala, which renumbered it #30. SHLC held on to the 30 for less than 3 years before selling to another rebuilder/reseller, Georgia Car & Locomotive. GC & L found a buyer in Barfield Lumber, located in Polk City, Fla, not too far from its original owner.

Later operated by Illinois Southern, which suffered bankruptcy and was succeeded in 1921 by the Missouri-Illinois. In the 1920s, several of the class went to work for the Arkansas Southern.
