>They are in fact 460km apart
Yes. I went through this in the threads earlier. This is my first post >>274773
The explanation is, from a post I received one bread later.
That the manor (building) itself in Austria was named 'Black Forest'.
I thought that was a possibility, because Black Forest as a geographical location didn't fit.
It was confirmed in that >>275181 post I linked, along with a wealth of information that explains the background of the estate sale.
That >>275181 post is definitely worth a look. Insider stuff, IMHO.
