This is the Labourdette-Halbronn double hull triplane torpedo bomber of French origin 1918-1920. About the reference . This machine is almost always referenced as a Labourdette-Halbronn triplane (look at the RAF Museum Thesaurus). The only reference of a designation is in Davilla French aircraft of the first World War, where two variants are given.
The H.T.1 is described as the original (prototype) machine which was followed in 1919/1920 by two examples of the H.T.2 allegedly a more powerful version of this machine.
The H.T.1 had two Hispano engines of 200 hp each. The H.T.2 had two appreciably more powerful engines, Lorraine rated at 350 hp each.
