Hi there, Harrier Bill. Having had a good look at the photos, it seems that the fuselage length aft of the wing would suggest that it's a Wellington. As you pointed out, the upper turret on the Warwick was situated further back. Also, the apparent 'turret' seems rather small in diameter to be a gun turret, and there isn't much evidence of the 'turret' bin inside the fuselage. Also, the structure that is clearly visible is in about the right place for the astrodome on a Wellington, but it looks too large to be a standard astrodome, and appears to possibly have some sort of former or framework. I can only suggest that it could be a Wellington T10, or perhaps one of the other Marks that were converted to crew trainers or transports, particularly those operating in the Mediterranean area.
