Im with Lee and Jens on this as well, that blade is Continental European and most likely Solingen into the 18th century but as early as late 17th....it may well be Netherlands as well and definitely a trade blade. As Jens notes, a southern type feel to the hilt, and I have seen this type metal on patas of this age, which were also of the same regional perspective.
The pata I refer to also had a very early blade, with markings of 18th century style, a broadsword blade, which was also mercilessly sharpened over many years.
A really attractive solid and honest example, all the better in this rough as is condition, to me history itself stands proud in this one!!!
Nice going Emanuel!!!
All the best,
Jim
