Thanks for your help! I think I've found something.
It is some paperwork
from the Sri Lankan government. Technically it is related to Ozone certification, but attatched to the end from pages 10 to 33, is what looks like an official list of which estates belong to which regions. I don't know if it is complete, but it does list Kenilworth. Apparently it is stylistically Kandy tea, but the actual estate is in Nuwara Eliya. To add confusion, it appears that the factory
where the leaves are processed is in Hatton, which is in the Dimbula region... can that be right??? A fusion tea, maybe.
