Lionhilt Broadsword 17th Century?

[AHorsa]

Thank you gentlemen.

I cleaned it with a small wire brush (for gimlets). Luckily the rust or patina was thick but very easy to remove. On other items it didn´t work with that method.

Intererstingly there are remains of glasslike black material in some of the carves, which makes me think that maybe the structure was elaborated with a Niello technique.

Best regards
Andreas
