Great find Carlos!!
We definitely need to get envy added to the smiles selection. Yes, I would agree that it is Ilocano and probably from the late 19th to early 20th century. The scabbard looks to be covered in thin pieces of water buffalo horn. I was lucky enough to find a couple of these daggers but non with a blade of this length. My congratulations on this wonderful addition to your collection.

If you ever get tired of looking at this please keep me in mind.
