I have bought it in the UK up north, it was advertised on a local website.
Would make sens to find something like this here in the UK because of the Indian heritage.
This is how it was described.
'' 16th century Sacrificial Bell from Tibet , the chain is very long (55 inches) and heavy 3 kg, it is green of colour, the bell very small in comparison to the chain (each link has embossed mark) I have attached photos, It was given to me many years ago by my Uncle Timothy Web who i believe was given it after wining a fight (he boxed) and the chap didn't have the money he owed him so Timmy settled on the old bell (This was in the car park regularly at a pub in Wheathampstead). I did pop into Bonhams in Cambridge quite a few years ago and was told it,s Tibetan and it probably dated from 16th century) I have owned it for 30 plus years and Tim for 80 before me. The length of the chain is 88 inches long and the width of the bell is just over 4" and 5" high , it is extremely heavy. ''
