Yes Bernd, you are perfectly right. Funny my misspelling the numbers. My
fingers run too fast (actually my phone number starts with 2656...pfff!)

Thanks for the reference.
I just also received the PDF copy from David Weir and read the intro and
the conclusions.
Very interesting...the Itqiy-Zaklodzie-NWA 2526 continues.

BTW, I have a pic of my Zaklodzie slice (14.1 g, 50x45x2 mm).
Not the best quality but I'll sent it to you in a separate mail.
If you feel it is informative for the list and if you can host it on your
site, feel free to send the link.

Thanks again for comments.
