The gun pintle stands securely in the centre of the platform but there is no sign of the gun, either on the platform or on the seabed below.
The gun itself has been salvaged, though the pintle remains.
The internal armament of the helicopter comprises a pintle mounted 7.62 mm machine gun and a door gunner post for a 12.7mm general purpose machine gun.
Looking closely, a much smaller gun rests on its pintle alongside.
Off to one side, an intact 12-pounder stern gun lies on one side, still fixed to its pintle .
Staying on the seabed at this side of the wreck, you can see a small pile of chain, then two small gun pintles fallen on their sides before a larger gun platform and pintle, again resting on its side perpendicular to the wreck.
A little further aft, pintles and ammunition for machine guns and rapid-firing anti-aircraft guns lie on the seabed, with a gun and its armoured shield among the debris.
The hinges are flat straps across the front, which bend over the pintles and form a short neat strap on the back, ending in split curls.
