Hi Gavin,

Below is a comparison between a Malay greneng and the Javanese greneng in question. I think the Malay greneng below is a variation from the Javanese where the Dha on the Malay keris is at the normal position and the "bump" dha is probably a copy of the probably older Javanese style.

The difference is that on the Javanese examples (which is probably older), there is no Dha at the normal position, just a gap - which makes me think that the dha was shifted to the upper position on a third element that the "bump" dha style. Plus on the Javanese examples there is a gap between the ganja and the blade that resembles the gap on Megantara greneng.

The ri pandan style in your #3 and #4 in my opinion is newer development as many keris with this greneng style uses newer homogeneous steel that has no grains (probably late 1800's to early 1900's) rather than the older grainy wrought iron. (This is in the case where the keris does not use pamor - your #4 looks like it uses pamor). But this is just my amateur observation, I cannot demonstrate what I write here even as a hypothesis let alone a theory that can be proven.
