Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 45, p. 251 . See Locobase 13735 for a history of the CGN and read James Baughn's Pavement Ends installment on "Cape Girardeau's most obscure landmark," SEMissourian, posted 24 March 2010 and retrieved from [], last accessed 16 January 2012. Works numbers were 41167-41168 in February 1914.
These didn't remain with the CGN for long before going off to the Saint Louis Southwestern and very soon to the San Antonio, Uvalde & Gulf as their 8-9. Eventually, the two were placed in their own class E-63 by the Missouri Pacific and numbered 928-929.
