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 .
