UK National Identity Card issued during World War II

As WWII approached in 1939, all UK citizens were required to sign the National Register, after which everyone received a National Identity Card. In most parts of Britain it would have been difficult to use your rations book for food etc. without your NID card. On Tiree, however, this is unlikely to have been an issue as everyone knew everyone else, and might explain why Christina MacKinnon of Balephuil/West Hynish did not need her card until 1942. NID cards were abolished in 1952.
