Sumatran / Bugis ID

[Moshah]

Good day guys.

This might be a rather foolish thing to ask.

But then again, I was neither good at IDing blade's origin, so here it is.

Could you guys ID whether this blade's a Sumatran or a Bugis?

It was in the posession of a German living in the Indonesia, who bought this 40 years ago there. Perhaps some of you guys have seen this blade...

Thanks in advance.
