Dagger ID Help Needed

[Robert]

Here is what I believe to be an Ilocano dagger from Luzon. It has some markings on the blade that I have never seen before. Grip is horn with brass fittings, inlay and I believe brass dots which can be seen in the last picture. It also has a bone piece fitted into the very end and held in place with a small brass pommel cap. I'm not certain that the scabbard is original to this dagger or if it is a later replacement. The only pictures I have are from the auction. I will post more when it arrives. Below are pictures of a knife that I have that I believe to be of the same origin with a very similar hilt. The fittings on the knife are brass with a silver inlay in the grip. All comments welcomed.

Blade length 8"
Blade at widest 1-1/4"
Hilt 5"
