Sanshikidan (三式弾, "type 3 shell") was a form of ammunition: a World War II-era combined shrapnel and incendiary anti-aircraft round used by the Imperial Japanese Navy. The type of layered construction of the warheads were generically referred to as Beehive rounds. The shells were intended to put up a barrage of flame through which any aircraft attempting to attack would have to navigate. However, U.S. pilots considered these shells to be more of a pyrotechnics display than an effective anti-aircraft weapon.
Condition wise these are in good condition, small evidence of coral pitting towards the lower sections of these shells, these shells have some excellent history and are very rare items for ordnance collectors.
