Made from a 76mm OTO Melara artillery shell with heavy machine gun cartridge center post. The 76 mm Melara was used by over 60 navies post 1964 including the Israeli. This memento was made ship board by a sailor in one of those navies. Carrying on the tradition which evolved from scrimshaw and whale bone sweetheart souvenirs. Additional markings could perhaps identify which navy used the shell. Expected age character and patina. First such naval example we have offered.
