Hi Valjuhn,
I found your thread only today.
As Jim has sad, this is a Venetian sword, which is confirmed by your statement that it was excavated near Friuli. It is of Venetian make and dates from the late 15th c., ca. 1480-90.
You will identify your type of sword among a group of four displayed on the right in a photo from the Doges Palace at Venice; they are dealt with in
Armi Bianche, 1975 (attachments).
Medieval Venetian swords of slightly differing, more common type are referred to in
