Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 62, p. 378. See Yale Snowden in collaboration with H G Cutler, History of South Carolina, Volume V (Chicago: Lewis Publishing Company, 1920), p. 79, as digitized at [] . (Thanks to Chris Hohl for his 9 May 2015 email and spreadsheet showing that the proper ID for the owner was J F Prettyman.) Works number was 53208 in April 1920.
