Hey Lew. That bottom one looks like a peninsula blade to me too and i would guess Terengganu as an origin (Kai Wee and Shahrial, jump in and correct me if i'm wrong). It's a sweet blade BTW.
But that top one looks more like a Bali keris to me. Could be wrong, but that's my feeling.
How to hilt these i think involves other questions. I realize the difficulty in getting sheaths for these here in the states. Do you plan on eventually getting them fully dressed? If so i think the choice of hilt is somewhat dependent on how you sheath them as well.The full ensemble should be completely harmonious with it's parts. If you don't plan on having sheaths made i would say it is really up to your personal tastes since there are quite a few appropriate styles for every origin. Also depends on how much you are willing to spend since hilts can run anywhere from $30 up into many hundreds of dollars.
I will PM you on some sorce possibilities.
