Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 31, p. 28 Works number was 31691 in September 1907.
6 later was converted to using Southern valve gear, which had been patented by designer William S Brown in 1906.
