i still very much doubt the authenticity of your claim, although i am not saying that you are wrong, from what i know, aged sandalwood (50 years or more, are all exported), yes a 3 ml oil goes for 250.00 british pounds, and you can find it in some quarters, the nilgiri oil that you mention is not of the mysore variant, there are too many shops in karnataka that claim they have the government crest, i've had luck with the authentic karnataka shop in chennai, and paid a fair price for what appears to be oil from 30 year old in the past, santalum album of the mysore variant you may find plenty, but the real majestic smell always arises from aged wood.
cheers.
