These Anti-Aircraft guns were fitted in both the Littorio and Dulio classes. These guns were mounted in a quadrilaterally-stabilzed mount, and usually housed in an enclosed oval gunhouse. This gunhouse had negligable armor, and exsisted mainly to protect the gun and gun crews from the blast effects of the main battery.

These are standard Master barrels- machined from brass, with an elegant taper to the barrel and a drilled muzzel.
