But you know, one thing is the smith's name, another thing is the genuineness of the mark.
You would have to check other swords made by Sacchi, to conclude whether the mark in this one belongs to him or if we are facing one of countless signature copies.
This because the lettering doesn't look like a keen job to me in the context and i wonder about the
double L ROMANNA term; one of these popular allusions, not exclusive of this smith ?
But don't pay much attention to my remarks, Skarts

. I am far from having the real knowledge. All i wish is that your blade was forged by the aledged master
