Italian submarine Barbarigo

Barbarigo was a World War II Italian Marcello-class submarine built for the Italian Royal Navy (Regia Marina). The submarine was converted into a transport to carry materiel between Germany and Japan in 1943, but disappeared on her first mission in that capacity, sometime after 16 June 1943.

The Italian Government issued a 5 Lira red adhesive revenue stamp featuring the Barbarigo. Inscription on the vertical stamp is "Sommergibile BARBARIGO/ INA GIL". exact purpose of this stamp is uncertain but may have been a tax or a charge for mail carried on board the vessel.
