I think you and others have effectively established that this general style of knife existed in the Philippines, and that was known before the present post and is not really an issue. The question comes down to whether this is a predominantly Spanish style or a Philippine style. If it is unique to the Philippines, then I need look no further. If the style is predominantly Spanish, and given the military inscription in Spanish that may be a logical deduction, then the possibilities are much broader. That's why I'm looking carefully at the particular characteristics to see if they match common experiences with other Philippine knives of this variety. If not, it could be an uncommon example of a Filipino knife, or an example from somewhere else in the former Spanish Empire. BTW, I have had no success in tracking down the regimental number.
