The National Museum of Computing has finished restoring a Tunny machine – a key part of Allied code-cracking during World War II.

Tunny machines helped to unscramble Allied interceptions of the encrypted orders Hitler sent to his generals.

The rebuild was completed even though almost no circuit diagrams or parts of the original machines survived.

Intelligence gathered via code-cracking at Bletchley underpinned the success of Allied operations to end WWII.

Restoration work on Tunny at the museum in Bletchley was re-started in 2005 by a team led by computer conservationists John Pether and John Whetter.

Mr Pether said the lack of source material made the rebuild challenging.
