thanks Matti and Chris.
To make the link, the map I showed in this link
http://forum.12oclockhigh.net/showthread.php?t=40452
Came from this aircraft, it was found on the site after the crash, and this map was kept 74 years by a local inhabitant.
So, yes, it is strange in fact that it is written in English, on a German map.
and BTW the crash site has been located..
Rgds to all;
