Handley Page Halifax bomber

There are none.

After the war, all the surviving Halifax bombers were destroyed.

The aircraft shown, an original Halifax, was retrieved from a lake it had crashed into and taken to RAF Museum, London. The decision was taken not to restore it, as it was too fragile and little would have been left of the original airframe. It cannot be moved due to the extreme fragility of the aircraft.

One other is preserved as a crash site.

Reconstructions
The only technically correct Halifax in the world is in Canada. A Restoration project in Canada at the RCAF Memorial Museum produced a full reconstruction of a Halifax - officially NA337.

NA337 was shot down over the fjords, but the Halifax Aircraft Association managed to raise it in 1995 and transport it to Canada. Unfortunately the original parts were rarely salvageable, so the engineers crafted replacements and used parts from other aircraft. As a result, there is very little of the original plane left, but if you want to see a Halifax as it was, this is your only chance.
