I guess most of you will already know this, but there are two TSR2s still with us:
The second airframe is complete and preserved at Cosford, while Duxford has the fourth (or fifth, I'm not sure) airframe which is unfortunately not complete. It lacks engines and a lot of internal stuff, but it still looks the part though!
In addition to these two airframes the Brooklands Museum has a TSR2 cockpit section that was used for pressurization testing.
