Lionhilt Broadsword 17th Century?

[AHorsa]

Dear all,

allow me to fetch up this old thread. It´s now nearly 10 Years I own this piece and it still won´t let me go. From time to time I do a bit of research on it and my biggest dream is to find a painting showing it´s owner with the sword I know it is very very unlikely, but I am sure such a painting once existed. The question is: did it survive and is it listed somewhere...

But anyway: I just stumbled over a picture I saved as a reference years ago with the comment "Sweden, 1660-90". I´ve found several swords with similar lion cross-guard, many of them indicates the Netherlands as origin but there are also pieces with other provenience. But this is the first time I found this wave-like decorations on the guards. Also the tool used to decorate the stylized head seems to be similar to the one used to form the lions coat. Maybe this can be a another hint to its origin.
Sadly I can´t remember where I saved it from, only that it was a (Swedish?) museums online gallery without more information.

Does anyone of you know similar examples?

Kind regards
Andreas
