Rare cased map reading compass by Breithaupt Kassel

Rare large and heavy compass complete with its original brown case. This is the largest compass which would be used in the field and uis easily twice the size and weight of the normal Wehrmacht issue marching compass. 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.
