Hi Rick.
Yes, I think so. The blade form is consistent, with a "peaked" clip to the spine and a small "bulge" on the cutting edge just in front of the guard--both highly suggestive of Ilocano work. The multifaceted brass ferrule with small brass guard is also in keeping, while the horn hilt with a groove for the little finger is typical of Ilocano work. The carved pommel is an uncommon variant IMHO, but the peined tang is very common. The thick leather sheath with a "rondel" at the throat is also a fairly common Ilocano style.
While few of these features are purely Ilocano in form, it checks all the boxes for me as Ilocano in origin.
Ian.
Addendum: In thinking about your pommel, I was reminded of a thread a while back where a similar pommel was discussed and the suggestion was made that it may represent a porobiscis monkey--see
here.
