Kubur,
I am sure this thread will soon receive plenty of responses from those, who have studied these old backsword blades a lot better than me. Comparing your image to those published on the Passau wolf it seems to fit markings associated with the 16th and 17th centuries. The hilt to me looks like an older, 18th century hilt as well, so obviously the blade cannot be newer than that. 17th century seems quite plausible to me at least.
