Sword with Hussar blade + niello. Russian ? Austro Hungarian ?

[francantolin]

Hello. thank you Fernando
Yes, sometimes...
That's why I asked if someone already saw this one :

It can be a militar common monogram like the Prussian swords with Wilhelm II empereror monogram on the hilt(1)

Or rare like the russian hussars impérial guard monogram(2)

Or a personal-single nobleman monogram (3)
