You have a rare piece there.
I think the "Lurban" might actually be "Lucban" as in Gral or General Lucban/Lukban. This looks to be made during the beginning of the Philippine-American War 1898-1901/02.
General Lucban/Lukban was a great Philippine (Tagalog) General of the Spanish-American War and the subsequent Philippine-American War. He was renowned for his intelligence and cunning in war, like many others.
A nice piece of history! Also in great condition, though I wonder if the scabbard was later made (better pictures would help determine). This piece is similar to one I have (with more historical info):

If ever you want to throw it in the trash, just let me know (I'll crawl back behind the garbage cans now

).
