Parts of a pusaka keris

[Ian]

Esteemed and learned colleagues of the keris,

Please help me understand the significance and meaning of the components of the bilah and ganja (as illustrated in the attached diagram). My interest stems from gaining a better understanding of the Moro kris and its history.

Can you explain what the various components of the "elephant trunk" area represent: the praen; sekar kacang/telale gajah; jalen/ilat baya; and lambe gajah/jalu memet on one side; and the ron dha nunut on the other side.

Also, on the ganja, can you explain what the following represent: the cocor; sira cecak; kepet urang; kanyut buntu; padakin; wawungan ganja; and the three components of the greneng (ron dha, thingil, ri pandhan).

Lastly, can you point me to references explaining how these elements came to be arranged in this formal manner for a pusaka keris.

Thanks for your help.

Ian.
