Its full military name was the Telescope Identification Ack-Ack Mark III, but those who used it knew it more simply as a rangefinder-heightfinder.

Eden Camp, the award-winning wartime museum at Old Malton, North Yorkshire, has been presented with one that is in pristine condition, even though it dates from 1941.

"All that was missing was the tripod - but we've found exactly the right type in our stores," said museum archivist Nick Hill.

"There can't be many of them left, but during the war they were invaluable and were often operated by women because they had more of a deft touch with them."
