Yup, I've always enjoyed that one. I'm pretty sure I still have a tin left, so I need to review my supplies. Sutliff made one quite similar, Westminster I think it was, not to be confused with the G.L. Pease blend, but not currently available so far as I can tell. But London Mixture was/is one of Dunhill's best, mild but not bland, with nuance and a good burn.
