Sword c.1500 year based on sword from New York.

In my opinion this sword contains features of type XVa and XVIIIa.
Blade is stiff and handling is very easy.
Scabbard is based on original scabbard from similar period.

There are 4 engraved sides on the pommel (made by Jacek Doliński @angusmetalsmith):
1. JESUS
2. MARIA
3 i 4 (sides) some kind of lily

The museum says 1190g which seems too little to me.
There are often mistakes in museum descriptions – weight or lenght.
The Cluny sword weighs similar but has a pointy, noodle-shaped blade.
And this blade from Met Art doesn’t look too thin and it is wider, especially if we look at the tip.
Only blade weight about 900g, crossguard 150g, grip 70g, so 70g left and it is impossible that pommel should weight 70g.
Even it is hollow, the weight should be about 200-250g because pommel is very big.

I added peen block because was very common with similar type of the pommel.
Unfortunately we can’t see that, it is or not. The perspective of the photo of original sword doesn’t allow us to see it.

Balance is very similar to Castillon swords from group A.
