Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 62, p. 327+. Works number was 52922 in January 1920.
This logging Ten-wheeler was sold in March 1927 to locomotive rebuilder/reseller Georgia Car & Locomotive, which sold it in October 1928 to Groveland, Florida's J Ray Arnold. The lumber company later sold it to the Macon, Dublin & Savannah, which was then part of the Seaboard Air Line.
