Well, here's the provenance for you, John. Better print it out just in case you ever decide to sell the pin.
The khukuri pin was commissioned by King Tribuvan 200 years ago to be manufactured for the king of Siam who was to visit Nepal. The kami who made the pin was 128 years old, and was said to have magical powers. The knife was made and presented to King Tribuvan. It was held in keeping in the Royal Vault, awaiting the arrival of the king of Siam but political unrest and upheaval in Siam resulted in the cancellation of his journey.
The pin remained in the Royal Vault for 130 years at which time it was stolen by a dishonest Royal Accountant and ended up on the black market in Assan Bazaar where it was purchased by a blind but very weathy Newari by the name of Rajeev Shrestha. A servant of the Shrestha household stole the pin and it ended again on the black market in Assan Bazaar where it was purchased by a Bhramin dwarf by the name of Sudir Upadhaya.
The pin remained in the Upadhaya family for 50 years but the family fell on hard financial times and had to sell the pin to an Indian sauji named Subesh Bancharee who had a pasal which handled fine antiques.
I met the Indian Sauji in 1984 and tried to buy the pin from him but he wanted too much money for it -- $8000 which is not bad for a 200 year old pin made by an ancient magical kami and in the Royal Vault for 130 years but still too high for me.
But one day while visiting Mr Subesh's pasal we engaged in an afternoon and evening of drinking khukuri rum. Mr. Subesh was a compulsive gambler so when I felt the degree of intoxication was at the proper degree I challenged him to a game of bagh ra beera.
Being a westerner he thought he could beat me at the game so was willing to wager the pin against two thousand US dollars. Little did he know that the Sherpas had taught me the game and had honed my skills to such a fine degree that I could beat almost anybody in Nepal, especially a drunken sauji.
I won the game and I won the pin. It remained under my bed guarded by the infamous dust bunnies for 19 years until I gave it to you.
Now that's a provenance!
