RAF 'Lapel' Bar Compass
Flat bar type compass in a rounded diamond shape. Luminous dots to indicate North and South. There is a hole to the centre to enable the user to tie the compass to a piece of thread. When hung in a glass of water the compass is steadied and will point North. These were intended to be hidden inside an airman's shirt collar or jacket lapels to provide a useful escape or evasion tool in enemy territory. Possibly not too practical given the compass is only stable in water! Single. Very good used condition. Stock code E19793.
