Here is a quite old beladah belabang, the sabre of the Malays in South Borneo.
This one has a heavier blade shape than the later ones. The hilt also has a more distinct Borneo look than the ones from the late 1800's which more and more resembled European hilts. Also the vine motif on this blade is quite different than the later ones.
Together with the one Charles posted in this thread

this is probably one of the earliest versions.
