I don't remember where I got that, but I like to collect pictures, as we see it is useful!
We had two connected threads in the past,
one on koummiya
one on Moroccan pistols
And I have seen some swords with the same decorations, paneled bones and semi-precious stones inlays.
My idea / opinion is simple, some of them have bad blades or fake locks, they were made for tourist market at the end of 19th c. and beginning of 20th c.
Others have very good blades and good locks (like yours) and they were made to be used in fantasia or other events...
