Data from [] (accessed 1 December 2006), a website devoted to the Tramway Tarn-Garonne (TTG).
Although the site shows the locomotive, it does not specifically state that the fourteen Corpet & Louvet engines were built to this particular specification. Like many French locomotives, these Corpets had Serve fire tubes with internal fins.
In fact, the TTG site notes that C&L locomotives ranged widely across the Freycinet Plan secondary lines that sprouted all over France after passage of supporting legislation in 1879. Planned for 8,700 km (5,400 sm) of narrow-gauge lines in all the sub-prefects in France, the network nearly reached that goal before its completion in 1914.
The TTG itself operated between the Tarn and Garonne rivers in southwestern France. Its principal hub was Montauban.
