Hi Bf,
If you take a closer look on then first shot, you can notice another mast between wreck's fin and upper part of fuselage. There was only one such a place in Poland, and Warsaw: Transatlantic Transmitting Radiostation Babice (website in Polish:
http://hamradio.pl/wiki/Nadawcza_Radiostacja_Transatlantycka_Babice) - another one is in Sweden, but I suppose it's not the case
. I'm convinced the wreck lays at Warszawa Bielany airfield, or very near to it. The row of ten masts is a few clicks West of the plane in subject. Unfortunately, I can't asist you with it's identification.
Cheers,
Pawel
