WW2 German Luftwaffe Mapcase ( With British Officer Name )

A 1938 dated Berlin maker marked mapcase in the chocolate brown of the Luftwaffe.
This early style of mapcase has the name of a British officer ' Capt. EAJ Edwards ' written onto the underside of the flap. Captain Edwards must have evidently captured this piece of German equipment & may be identifiable by his middle initials.
