I'm trying to find out if this map case is German or Bulgarian. It bears name (ww2 and before style writings) of Bg low rang officer. At that time a lot of German or German style equipment was used by BG army. And a lot of 1945 wartime trophys from German army can be found allwso in army use after the war.
There are no markings or stemps. So what is the experts opinion?
