It's a naga form keris .
The blade 'seems' old .
I can't tell the pamor without seeing it in a proper stain .
The hilt seems to be a Surakarta form .
Again, this blade confuses me; is it Mataram style, or Madurese ??
The pendok seems to be repoussed on both sides; this is not usual in my limited experience .
Restore ?
No .
Maybe get the blade stained; that's all I would suggest .
