WWII German Luftwaffe Wrist Compass- This is the AK 39 wrist compass used by the Luftwaffe. It has a soft dark gray leather band that is in excellent condition. The compass is produced in bakelite and is liquid filled. This example seems to be a bit low on fluid. The face has some wear and is a bit faded. The reverse is also marked Fl 23235-1. Good condition!
