G'day everyone

Thank you to those who responded to my previous posts.
To me the end of this, earlier style? scabbard looks like a scorpion stinger, possible perhaps? as their are species in bourneo. eg: Heterometus spinifer, Asian forest scorpion. The wood of handle is nice I think. Blade is laminated?
Blade length: 16 3/16 in
Handle: 7 in , shame about the crest broken off
Any ideas regarding origin and age appeciated, Thank you.
Kind regards,
Daniel
