I think, but I'm not 100%, that it's the fuel tank in the fin, which can also be found on the A310, A300-600R and possibly the A340. I don't think any other manufacturers use the "empty" space in the tail fin for fuel. I remember reading Boeing were considering it for the 777X - don't know if they rejected the idea.

Yes, the 747-400 has fuel tanks in the verticle stab as does the MD-11. And its true the the Vickers VC-10 was the first aircraft to employ this technology much to its advantage in being able to manipulate its CG in flight to optimize cruise performance. And what a fantastic airplane the VC-10 was.....
I am not sure if the A330 does or not, but it is certainly possible. One could visit the Airbus website which has wonderful cutaways of their aircraft. Nice site in general actually.

The MD11 has a fuel tank in the horizontal stabilizer used mainly for control of center of gravity. There is no tank in the vertical stabilizer. The same goes for the A300-600 and A310, fuel in horizontal stabilizer (called the trim tank) but no fuel storage in the vert. stab.
