The Victor had much of its BombNav system removed. The precision GPI6 had been replaced by the older, simpler GPI 4. The ballistics computer had been removed. The armament electrics had probably been stripped out. The Vicotrs had been greatly reworked by BAE or who ever, including clipping a fair bit off each wing.
The Victor 2 had never been a bomber, only a missile carrier, so it did not have any bomb gear and probably no bombdoors. It did not have the Vulcan Heading Reference System either.
The Vulcan 2 Blue Steel had come with two sets of bombdoors, one for the missile body and one for the free-fall role.
I am sure a Victor crew will be able to confirm this.
