Data from Charles Alfred Oppermann, Traite Complet des Chemins de Fer Economiques D' Interet Local (Paris: Imprimerie Pillet Fils Aine, 1873), pp.153-154.
In the melee that ensued after passage of the first French law to encourage development of rural, light-service railways, several locomotive builders offered examples of the kind of engine that suit the service.
Corpet was the successor to Anjubault.

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.
