[Rapier's Delight]

Hello all,

I recently posted about two at least partially 17th century small swords that shared many characteristics while still being rather different.

Yesterday a new one joined the family. This one, however, is heavier and in worse conditions than the other two.

What it does have, however, is a set of interesting engravings on the blade, which include what seems to be a mane, or writing, in a very rounded, almost modern-looking font.
I'm trying to figure out what may be written, but it's not easy, so I figured some of you may have some clues or thoughts to help my research.
