These guns were developed in 1930-1931 in order to achieve the maximum caliber allowed for Japanese cruisers under the Naval Limitation Treaties of the time.
All heavy Japanese cruisers built after 1932 were armed with these weapons.
The model was created based on blueprints, photos and historical documentation. No internal or functional parts.
