it seems a transition model around 1580, this type of blade was used on two hand swords between 1550 and 1575, the pommel and guard are of a later date 1580-1600.
the abrubtly stopping quillon finals are very unusual, you'd also expect (3 )curls here.
maybe the guard is a bit altered and shortened in the 16thC.
it's a beautiful unharmed original sword, congrats!
best,
