Thank you so much, Lee,
For posting this characteristic sample.
This is exactly what I described - though it sounds totally unbelievable at first (and sadly second) glance and feels right when handled, after a while the conglomerates start coming off.
These fakes are both highly criminal and dangerous. I was told that the Hungarians 'damage' and then bury them in dung heaps for months. The dealers pay them about 300 USD a piece. Imagine!
Your sword, of course, is in 12th c. knightly style. What a pity ...
Best,
Michael
