Yesterday i was at my friends house and i saw a map. He told me its a german period map of the city Brod in the middle (probably Slavonski Brod today) and the rest of the cities around. But i was suprised to see that over the map was added a new legend, and a lots of fortifications, PAK positions,... my heart stopped! And the best thing is that is the area that im planning to detect on! The legend was printed with red ink, and as soon as i saw the word "Geheimnis" i knew it was something that the army was used. So, does anybody have a similar map from this area? He didnt allow me to take a photo... and now im so intrigued!
