Luzon daga, wavy blade

[Sajen]

I am the new owner of this large Luzon daga or kris. Brass mounts with horn handle, laminated (?) slightly waved blade and worn leather scabbard. Overall 17 3/4''. Before I give my own age guess I would like to read what others think. Would also be very interesting what you think from where on Luzon this piece coming. Strong Spanish influence I think. Pictures from the seller.
