Thank you all for sharing information and opinion on this unusual P. Nabur.
I guess it is so atypical that it raises many questions that we can only speculate about, and I think that adds to the mystery and fun. The lost D-guard (or was there ever a D-guard when this piece was put together? Did a previous owner saw off the guard to suit his silat style? Or maybe the owner simply hated the D-guard and quillon?
) is part of the history of this piece.
At the end of all these, I've grown to appreciate the uniqueness of this piece even more. Add to that the beautiful blade, horn hilt and complete scabbard, this piece is going to stay with me for a long time.
I am going to keep it as it is because I think it will make a very interesting conversation piece.
