Help Needed To Verify The Identity of A Golok

[mohd]

Hi pals, we the Malaysian knife collectors are in the process of identifying the various types of Malaysian parang, golok and pisau (i.e. parang, golok and pisau which are originated from Malay Peninsular, Sabah and Sarawak).
And we came across this golok which was claimed as a Malay Golok Circa 1850.

Malay Golok C 1850

One piece horn grip of faceted section and finely contoured form. Tapered faceted copper base ferrule. Very heavy 11 3/4 blade of thick wedge section with chamfer to the top, one side. Shows smooth dark patina over old sharpening and few edge chips.

We know that this is a golok!
Anyhow we just couldn't verify whether this is actually a Malaysian or a Indonesian or a Philippines golok!
The blade looks like a Malay Peninsular work but the crude choil at the ricasso, the many faceted collar bolster plus handle and the through tang screwed/peened to the pommel looks more like a Southern Philippines work.







IMVHO this sort of handle and fixtures were not done within the Malay Peninsular, Sabah and Sarawak especially in circa 1850.
Your kind help to unravel the mystery (i.e. to us ) that surround this golok is highly appreciated!
Thanks a lot in advance
