Help with the Moro Kris/Kalis/Sundang

[Interested Party]

I picked this one up a couple months ago and haven't had time to post till now. I believe it is a Magunindanao keris blade. Could the fittings be Maguindanao as well or Mindanao? The pictures are from the seller. Overall length is 25 3/4"/654mm, Blade length is 21 3/4"/554mm, Width 1/2" past gandik 1 1/2"/44mm, width just before tip 1 7/16"/37mm. The blade needs a clean and etch when I have time. The tip has snapped at some point possibly due to cold shuts forming while the smith attempted to create a chevron pattern at the tip from two twisted bars. There is a center ridge line that shows prominently for the first 2/3 of the blade then fades.

As far as the dress goes there is a single copper? asang asang with no signs of a second. The attachment for the asang asang is much less oxidized than the asang asang itself or the strap down the handle. Brass ferule. The wooden handle probably had rattan wraps at one point and there is a possibly silver collar with simple okir. The pommel cross section is ovate. There are two incised lines around its circumference. Attached are two similar pommels I found in the archives and links to their threads:

Any guesses on which Moro groups owned this kris? Does it show characteristics of different groups? Estimates on the ages of the components?\
