some side notes;
the sword can be 14thc..... but also as late as 1450, which I count a very good probability.
the coat of arms is of
d'Aubusson de La Feuillade Family from france. see Attachements.
in the French language for d'Aubusson de La Feuillade

maybe and with some Imagination the sword of Pierre D'Aubusson! it has the same blade Geometry and pommel as on a 15thC drawing of Pierre D'Aubusson.
Pierre d'Aubusson, Grand Master of the order of Knight hospitaller, St. John on Rhodes in the late 15 thC.
you should try to find the original of this reproduction;
