This is a 1/350 scale 3D model of Lion Class Battleship "Y" turret's gun director, which is positioned on the turret roof to the port side. This gun director is specific to the particular class and is only used on the "Y" turret. The turrets are also available on my shop. Recommended for scratch-build and kit-bash Lion Class Battleship models.
