Jim, thank you for your learned insights here.

Unfortunatly I cannot fully read the date on this Guom example... 17 is there and a partial 0.

The Kamer stamp is partial too... looks like "H".

There are numerous other European stamps to the blade on both sides, Equal armed crosses at each end, effectively encapsulating the date markings. There are crescent symbols that are perhaps "moons" and some other hints of markings I've yet to reveal under the thick old build up on the blade.

Length, blade is 64cms.

When considering this Preanger Gobang I had many years ago with a blade just under 51cm long, it is easy to see how the blades were trimmed to fit native applications.
Further to this, the "H" on the Guom is not large like the "A" on the Gobang and it is below the VOC markings, not above.
What all the orientation means or leads to, I cannot say.
