Large Bali or Lombok keris for comment

[JeffS]

I purchased this large keris from Artzi, not yet arrived. The gerantiman hilt with grip checkering and long 52cm heavy blade seems to be intended for saber grip providing some slashing capacity despite the blumbangan. As with my other Balinese keris, the hollow edge stops short of the tip, leaving it thicker. I've seen it suggested that is reinforcement for piercing, though I am skeptical. It appears pamorless which I understand would be unusual in a Balinese keris. I'm not sure about Lombok. The sale page indicates early 20C but I wonder if it might be a bit older. What dhapur is it? Any comments and observations would be very welcome. Photos are from the seller.
