Hi Fernando

,
I think this is a combination of 3 sword parts (or possibly 2....ie the hilt/blade of one sword and, a replacement guard). The blade to guard seems ill fitting. The 'patina' (darkened area) on the inside of the guard that buts up against the hilt, suggests that the original hilt was a larger diameter. The blade looks to have been shortened .... the fullers seem too close to the 'point' (perhaps due to the original tip being damaged or perhaps to adjust the 'balance' of the sword after receiving its 'new' furniture ). Looks as if this 'composite' was made some time ago, how does it 'feel' in hand ?
All the best
David
