Great read, thanks for posting it. I bought my first high grade pipe, an unsmoked Upshall, from Bob Hamlin around 20 years ago and I fell hard for his PCCA blends (made by McC) soon after. He also introduced me to World Tobac Ltd. #341, an incredible oriental blend he though enough of to have McC tin up 100lb for him (it was a non-McC bulk blend).
