Data from diagram Loco: 10, Societe Alsacienne de Constructions Mecaniques from locomotive book supplied by Dany Machi up at [] as
Diagrammes des machines SACM construites a GRAFENSTADEN (October 2007).
Clearly related to the Midi 2-4-0s shown in Locobases 11361, 15574-15575, this design was just a bit bigger, had a slightly longer wheelbase, larger grate. Tweaks, really, on a basic pattern.
