I had to think for a bit about how to respond to this statement.
I have been hanging around internet pipe groups for about 8 years now, I have seen much discussion of the merits of various brands. I have seen people swear by Dunhill/Peterson, etc., and other folks claim they were overrated. But I have never seen anyone claim that you couldn't tell a Dunhill from a Dr. Grabow in a blind smoke test before. That's a new one on me.If you were blindfolded, and didn't know the name of the pipe you were smoking, all the horse shit with prestige and product status would be eliminated, and a Grabow would likely be preferred over a Dunhill, etc.
