Boulton Paul 'Dumbell' 'turret'

[PMN1]

Not sure if this is exactly the right board but..

The BP designs to B.12/36 and P.13/36 both used a

'patented Dumb-bell type mounting which housed two Brownings to either side (total four), with the gunner housed in the rear fuselage. This arrangement, which was provided as a mock-up, placed the guns in stub winglet fairings in an attempt to reduce he drag penalty of a completely moving turret, while also eliminating the need for a massive cylindrical mounting as previously used on the BP's Overstrand bomber.

There are some drawings of the two designs in BSP but not much other information.

Has any more information on this mounting surfaced and how would it have actually compared to the standard manned turrets?

Well, that's different...

Would there be any way to crank weapons to clear stoppages ??

The patent says that the ammunition boxes are inside the aircraft, so the belt has to be fed around the hinge with 90 degrees movement laterally and the elevating hinge of the gun pod itself which has 180 degrees movement. Good luck with that!
