Hi Henri, interesting ensemble you've got there. The hilt is uniquely Salayar, "Pangulu Le'ngo" (le'nga) form, as it's called by the locals. The interesting keris blade, I cannot confirm. The hilt cup (pendokok, kili-kili) is Sumatran. The sari bulan sheath, may be Sumatran or Peninsular Malay to me. Overall a nice find, congrats!
