US Superior Magneto paratrooper wrist compass

Very nice early US paratrooper wrist compass by Superior Magneto. This is a rarer variant without the luminous marked dots on the bezel.
These compasses where also known to been worn over the sleeve, the shoulder loops, webbing, or at the ankle over the jump boots.
Wrist compasses were used both by officers and enlisted men. A very nice example that would be hard to upgrade.
