Data from Krupp im Dienst der Dampflokomotive (Essen, Germany: 1940), p 90. Works numbers were 1070-1071 in 1929.
In addition to its small coal bunker, this pair of six-coupled tanks carried 1/2 ton of oil fuel. Immediately after these tanks left the works, Krupp produced five Moguls; see Locobase 21275.
