Looking for some Kris info

[hockeysew]

Hey all- nice forum you have here.
I am looking for some information on a couple of items that I inherited a couple years ago. I was cleaning out my safe and decided it was time to find a bit more about them.
I know that they are quite old and do not doubt the origin as they were obtained by my grandfather in the Phillipines when he was in the service. I do know for a fact that he was part of the peacekeeping force there in the early 1900's plus served in WWI.

On the scabbard for the larger item there is a handwritten note that reads:

"This weapon was taken from the hands of one of the most dreaded Momo (or Moro?)
outlaws that ever was captured in Mindinao. His name was Monermdo (might be wrong-hard to read) and he had a large following of Momo (or Moro?)bandits. He with 16 of his band were killed by the 6th (section of note missing) near the Romain (?) River June 4th 1911"

This would have been the timeframe that my grandfather was down there.
If anybody has any knowledge on the history these may have I would like to hear from you.
How would I go about finding a value on them?
Or if anybody knows of a good resource I would appreciate it.
Thanks
A few pics: I can provide more detailed ones if you like.
