The Dunhills belonged to Alfred Hitchcock. Gus' Smoke Shop bought the collection from his family. I just happened to drop in while they were unpacking the pipes and as a regular customer, was offered first dibs.
I bought a couple of bents, which were quite small and pretty filthy, and that's the whole story. Not much of a thread there, I'm afraid, but another thread does occur to me and I'll post it.
