To me, this looks clearly like a Solingen blade... possibly engraved in Hungary. Pretty much the same "Hungarian" blade (made in Solingen) like the one in the Arabian Shamshir in the Ethnographic section:
As far as I know there were NO blade making centers in Hungary and ALL the "Hungarian" blades were made in Solingen or other places in Germany and Austria. As far as I know... but that doesn't stretch too far.
Does anybody know of any proof there were blade making centers in Hungary?
Does anybody know of a Hungarian swordsmith?
