Excerpt: "Handle might be more recently added."

A yogya palace guard, sporting a Solonese hilt....hmmm?
Possibly a recently replaced hilt?

2) 19th Century Yogjakarta Keraton Keris?

Excerpt: "It has a brass cover with the Yogjakarta Keraton (palace) logo."

Keraton logo on the pendok doesn't mean a keraton piece, right? I was told that pendok with keraton logo are readily available, for purchase.

As I'm new to keris, kindly guide me along. Are these keraton (palace) pieces?
