It is 10.25 inches tall. Legal to own. This is just a piece of steel. No powder, no explosives, INERT and legal to have piece of World War two and very rare equipment that was dumped out of aircraft on enemy troops. The round is complete with the HEAT head and the tail assembly and originally markings. They are tough to locate in any fashion and this one is a gem. These are two types of Air-Dropped Cluster Munitions used by the Japanese Army Air Service in WWII. This is the Type 2, 1/3 kg HEAT Cluster Bomb Type 3 1/2 Kg HE Cluster Bomb. One arming spool is off as shown in the images.
