Another Luzon bolo with carved horn handle

[Sajen]

Have had this Luzon bolo long on my watch list and have given some offers to the seller, at last we have found a price which was for both of us acceptable. The nice carved horn handle shows a ram and I think that this is a little bit unusual since I never have seen such a handle before. The sword is 24" overall and the blade is 9/32" thick at the base.
How you would call this sword? Itak, matulis? What you think is the exact origin on Luzon? Age? All comments are very welcome.
Here the pictures from the seller.
