Vintage Wittnauer US Compass WW2 WWII Brass? Bronze? Early military compass has seen better days. Looks like a silvery brass. Has a small dent on the cover as shown in the photo, and the glass needs replacing. The needle is jeweled for easy piveting but it needs cleaning and oiling for it to spin more freely. The lid clicks closed and the button pops it open nicely. Needs polishing if you desire. I think this ruins the patina, so I will leave it as it is. Wittnauer must be the same company that made the watches. Pretty cool!
