systems of obturation and firing are also similar.
The mounting consists ’of a bolster fixed to the deck

conical rollers being interposed, and clips which prevent
the slides from being displaced. The gun-carriage with
two brake cylinders runs freely under the action of recoil

For elevating, a handwheel operates a pinion that
gears into a toothed sector fitted to the gun. For training,
another handwheel is provided that works a pinion acting
on a circular rack around the bolster.
The recoil cylinder is hydraulic with constant volume ;
the piston-rods are fixed to the front of the slide, and are
supported at the back by angle-shaped standards. When
