Some pictures from the family album taken during the period of the first Mk7 IFTU in 1957.
B&W shot clearly shows the cutout for the Mk30 18" "Homing torpedo" that weighed in at 645Lb.
Machine blighted by the highly unreliable Alvis Leonides Major Engine which did not take kindly to being made to run for the purposes of the helicopter application in the opposite direction it was originally designed to. This de-optimised the location of all the oil galleries in the crank etc. The RN had 129 Mk7 of which 79 were written off in service. Weymouth bay is littered with them..
