Greetings. This is old sword (more like "tesák" in czech, which is a type of short, one edged sword similar to saber) of my family, heirloom, you could call it. My grandma, who allowed me to take it and restore it, wasn't able to tell me how long it is in the family. Here is a picture, I've no problem with posting more if you are going to need it.

Not to discourage further answers, but you might have more luck at r/swords, where they specialize in identification.
