The 3D design of this compact combat car utilized in the Spanish Civil War is noteworthy. Dubbed "Naval," it was manufactured at the La Naval de Sestao factory in Vizcaya. Initially, it was intended to be equipped with a 40mm cannon in its turret, courtesy of the "Rodriguez Arellano" model. However, production constraints necessitated that several machine gun variants be installed according to availability. Multiple models of these variants are presented: one featuring the 40mm cannon, another with the Lewis machine gun, and a third with the Hotchkiss machine gun. Additionally, there is a chassis variant equipped with both the Lewis and Hotchkiss machine guns.
