Two interesting petrol marine engines are on display in the Musée des Arts et Métiers. The Musée also have on display an 1887 scale model of a two-cylinder petrol engine. The museum's online information credits Fernand Forest as the 'auteur intellectuel et matériel', and Fernand Forest and Georges Gallice for the 'origine de l'oeuvre'. See here.
