I think it's a charming piece Montino It lacks the widening at the base of the blade but I still think it's Moro.
Between wars 1 and 2 maybe for vintage?
I don't know if it was made as a souvenir, but I doubt it, the wrapping on the scabbard looks too functional.
I would have bought it if I were at that sale.
Reset the handle and find a piece of gray MOP to fit that void.
