Scarce cased large Wehrmacht issue map compass

Rare large Wehrmacht issue compass. This is the largest field worn version of compass made by Gebr. Wichmann, Berlin. The compass is twice the size of the normal Wehrmacht issue marching compass and is flat and heavy. Meant to weigh down a map so it doesn’t blow in the wind. The compass comes with its original leather case. Very rare and hard to find large metal officers field compass complete with its issue case.
