Welcome to the forum!
This seems to be an old pedang blade; possibly pamor adeg - sharper pics would help to confirm.
The scabbard and the hilt are a more recent addition - pretty much the same concept as with Japanese storage scabbards. Thus, not that much of a loss.
The value certainly is in the blade and pics will help to address quality as well as suitable strategies for improved staining.
