The hilt of the so-called tameng Sari is called "ketam guri", or I saw it somewhere Madurese term as tongkol jagung.
WRT the keris, and if the keris in question is made state regalia of Perak, I think Tameng Sari was a "gift" from the Majapahit king to his son in law, Sultan of Melaka as its a tradition still practised by the Jawanese till today. The keris was then given to the chief admiral, dato Hang Tuah. That's why after the failure to ask mount Ophir princess for hand in marriage, the keris was retured to the sultan while hang Tuah moksha forever......
well, a lil bit of folk lore story to brighten up our day
