WWII BUTTON COMPASS

Buttons sewn on Uniforms but when removed may be used as a compass

( Compasses and other devises would be confiscated on capture )

The plastic version could be hung on a thread, known as swinger button. The other two button version would be put one on the top of the other as one has a pin in it's centre.
The top has a magnetic dot luminous, and two other luminous dots on the other side the same as the plastic version.
