Brekele, i would not place myself in Keris University just yet. I tend to think of myself as being more in High School as well when it comes to these studies.
It has been my understanding that many "Old Kerises" in Lombok were more likely to originate in Bali which ruled over and influenced Lombok for many years. Not to say that a Javanese keris could not appear there as well. But i suspect that this last keris you have shown is neither very old, nor from Lombak, Bali or Jawa. I could be wrong, but i suspect it is a more recent Madurese creation made in the style of a Bali/Lombak keris. Since it is made in that style i think you have dressed it correctly, but i would agree with Alan that Javanese Dhapurs would not apply.
