Golok or Pedang (Indonesian)

[Spunjer]

salamat, boedhi!
in your opinion, would this be an older piece, or a newer one?

btw, here are the dimension:
total length (in scabbard)= 30"
total length (sword)= 29"
blade length= 23"
handle= 6"

btw, i took the liberty to polish the silver fittings on the scabbard and hilt...
