Wooden map plotting board or Kartenbrett with contents

A very nice original wooden map plotting board as used by officers in the field. These wooden boards where used by officers to observe maps without making them wet or dirty. These where vital in the field and scarce to find! It comes with the original rubber band to secure the map with. The board comes complete with a bunch of map drawing templates and the original pencil. 
Very nice and scarce officer accessory, especially with the period contents
