Arthur is right. The "White Spot" is too big. I was told if you call it a dot in the presence of someone from the Dunhill company, they have a license from Her Majesty's Secret Service to kill you.
That is one of the pipes I bought from the Aaron Spelling estate while I was brokering the deal with SmokingPipes.com. I obtained it in May 2010 at the Chicago show, and never noticed it until May 2011 at the Chicago show.
I was sitting next to Frank Blews. He currently works as the Mac Baren specialist for their U.S. importer, but is a long-time tobacco and pipeman, having worked at several companies for decades, including Lane Ltd.
He spotted it right away. Then, when I compared it side by side with other Dunhills, I knew he was right. Aside from the "White Spot" being too big, they did a great job on the replacement stem.
