Karabela european?

[serdar]

I acquired a karabela sword from collection of one old collector, he described this sword like “turkish karabela 17. Century”.

What i can see is an old blade, wery high quality blade, with very good toughnes, and high quality of steel, blade that se lot of usage. Blade is similar to the shamshir blade, but it is not a shamshir blade, profile is diferent, and diferently angled, allso it has a markings on a both sides, something that resembles a crowns? Maybe?
And a 5 star mark that forms a cross, that is obstructed by the langets of crossguard but i tried to capture on photo.
Those stars i have on two more swords that i know 100% are genova made and from 15 century.
And i saw similar stars on mostly genova made blades.

Handle is replacement, but an old replacement maybe 17/18 century.

If someone has seen this type of blade, or those markings, or has some valid info, please do share.
Thank you.
