Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 23, p.232. Works numbers were 18719-18720 in March 1901 and 19362-19363 in August.
The 4 Moguls in this entry were essentially identical to the dozen supplied to its stablemate, the Vickburg, Shreveport & Pacific, in 1898 and described in Locobase 6079.
After careers of between 15 and 25 years on the A&V, all four entered second careers for other users. 437 was sold first to the Sumter & Choctaw in 1916 as their 101. 439 went to the locomotive rebuilder/reseller Birmingham Rail & Locomotive in 1917, which later sold it to Cuban company Mora & Zayas. Also located in Cuba was the Central Limones, to which the 438 was sold in 1926. 440 wound up working for Birmingham, Alabama's Newcastle Coal Company.
