This is a diorama of the Torpedine Semovnte Rossetti called “Mignatta”, the human torpedo that sanked the Viribus Unitis into the Pola's harbour in 1918.
The torpedo is completely scratch-build for Italiankits (www.italiankits.it). The harbour is fully built in plaster and the figure is a S.L.C. “Maiale” operator from Model Victoria.
