Not much dope out there on Dobie.
Found this advert picture which dates to 1955:
If I had to speculate, I'd wager that Tudor Special Light was likely a low-nicotine shag baccy intended for faggy rollups, but have no idea really.
Bought out by Godfrey Philips in 1956 and likely discontinued then, but not sure, what can be said? Purple prose with passioned glimpse back to an era undone. O! Sherlocking with magnifier zoom'd to bloom in on ghost notes floating ethereal, the smoke no more flowing.
Famously,
