Alessandro Anzani, an Italian who originally built motorcycles in France, later developed air-cooled radial aircraft engines beginning in 1909. First produced in 1911, Anzani built early six-cylinder designs in two sizes, with the cylinders arranged in two banks of three each. In reality, these were double forms of Anzani’s original three-cylinder radial units. Historical references differ in specifying important characteristics of the two models. However, it is likely that a later model of the six-cylinder engines was rated at 59.7 kW (80 shp).

It is believed that the displayed model powered the Farman Sport, Hanroit D I, and Caproni A aircraft. Larger models of the six-cylinder radial powered the H. Fabre, Morel, Caudron, Train, Deperdussin and Colombe-Ladougne aircraft.

Further research is needed to determine the exact model of the museum’s artifact..
