Hello Charles, I can only say that you would find it hard to acquire a nicer example of a Kalinga axe than the one you show here. The photo you posted below of the Apayao Warrior I believe shows an axe most would refer to as more of a Bontoc style. There is a wonderful thread on the Kalinga axe located here:

Best,
Robert
