WW2 RAAF Escape and Evasion Compass- Rotor compass in plastic pouch

WW2 RAAF Escape and Evasion Compass- Rotor compass in plastic pouch. Small rotor compasses were sealed in clear plastic pouches, or' bubbles' (now often discoloured) to protect them from humidity in the tropics. The compasses in the small round 'bubbles' were usually contained in escape and evasion kits. Others were placed in larger pouches which had cotton tape threaded through the top so the compass could be worn around the neck during operations. This example in VGC.
