The Imperial Japanese Navy introduced their single 25mm antiaircraft guns early in the war and only later fielded the twin and triple gun mounts. Lion Roar has released a set of 1:700 scale single 25mm guns with IJN 25mm Antiaircraft Guns Set II R7031. The set includes 24 single 25mm guns with 16 square base plates and 8 round base plates. Also included are 12 twin 25mm gun mounts but 14 base plates for the twin mounts are provided. All base plates have relief-etched anti-skid tread patterns.
