Not heard about this, but with a little research Charatan's blends were/ are rumored to have been made by Dunhill in the early 1970s from what I could find out, so there is some supposed connection.
Sound interesting but am Leary as I have been told these kinds of lies before.....its just like the old one you know.....just with cheaper parts and a higher price if you know what I mean.
If it does come to be I will be interested to acquire a tin or two, if for nothing else so I can have a good moan!
