What Is This?

[stewey]

Sometimes I post “What Is This?” threads on here for sort of a fun type quiz. However, this time I do need help in identifying something, and I know there are some ex-military types on here. I found this item in an “Army Book 64, Soldier’s Service and Pay Book” from the Second World War. Any ideas? The top horizontal line is blue, and the bottom one is black.
