Burma Railways locomotive diagrams posted on Flicker by Florian Grupp, last accessed 3 March 2012. Skoda works numbers were 516-520 in 1929. Henschel works numbers were 21632-21643 in 1930. (road numbers for first four were 72-75 and 477-484.)
A note on the diagram states that all E class engines were fitted with steel fireboxes.
According to the Florian Grupp, virtually all E-class engines survived World War II's Japanese occupation.
