keris in amsterdam museum

[Kiai Carita]

If the covering is copper it is unusual. As that the keris was the oldest and most precious in the gedong pusaka of the keraton, hm, nice story but unlikely to be true. As the keris has two sogokan it must have been made after the sogokan was incorporated in to the form of the keris so it could not have been the oldest keris in the kraton.
