Would be a nice addition for anti shipping missions. Most of these attacked convoys, but occasionally they got lucky and found a U-Boat.
Was equiped with a Molins "6-pounder Class M" cannon, a modification of the QF 6-pounder (57 mm) anti-tank gun weighing 1,580 lb (716 kg) fitted with an auto-loader to allow both semi- or fully-automatic fire, in the nose, along with two .303 in (7.7 mm) sighting machine guns.
Later version carried the even larger 32-pounder, a gun based on the QF 3.7 inch AA gun designed for tank use.
But a 6 pounder would be nice with 24 rounds.
Anyway thats my wish.
