Hi,
Almost identical blade re the profile and the IESVS MARIA mark,
http://www.fricker-historische-waffe..._2013_engl.pdf sixth photo down and the sword above the Cinquedea. This one in obvious better condition than mine as most of the detail in mine has worn off. On my blade there are signs of use i.e. the usual small nicks and the sword still has a bit of an edge.
Regards,
Norman.
