I recently purchased a 35 Dunhill root briar online. Upon receiving it I noticed that a quarter sized spot on one side is noticeably lighter in color than the rest of the pipe. Could this be due to the finish rubbing off from coming in contact with the hand over the years or is this a common natural blemish that has likely been there since production? My ocd wants to have a touch up done by J.M. over at Boswells but at the same time I don’t want to alter a briar produced almost a century ago. Any advice is appreciated
