Swiss saber with inscription "ANNA" (?)

[Jim McDougall]

Without looking further for examples, it seems the opposed dual application of names etc. was a convention often seen on Italian blades late 16th through 17th c. While obviously crudely inscribed by someone not necessarily skilled, and copying loosely this often seen manner, perhaps this Italian oriented convention was in mind.
Again, simply a hypothetical option toward possible scenarios.

The opposed configuration brings to mind the familiar 'sickle' marks typically attributed to Genoan origin, which are opposed dentated arcs.
