Magnate (nobleman) saber from Croatia

[serdar]

Magnatska sablja ili plemićka sablja, or magnate (nobleman) saber, from Croatia with provenance of use by croatian nobleman, as usualy with those sabers or swords, blade is trophy and much older than mounting, in this case i would say a military karabela? Blade, maybe italian, but not sure.
I have a yatagan with blade that is cut down from old sword and it has a similar markings.
Blade is very good quality, (pictures are very bad quality, but they are what they are ��) it has three grooves, sharp yalman, and damage marks from another blade, axe, or a mace?.
I would say that blade is 17 century.

Mounting is silver with nice patina, nice preserved velvet, one side is ornamented with beautiful baroque engrawings and set with semi precious stones, other side is made like snake scales pattern, on the chape there is a snake holding a globe in its mouth.
Tang is peened into the hilt, with some resin or filler inside.
I would put mountings on the second half of 18 or end of 18 century, maybe begining of 19 century.

Any thoughts are welcome.
