@georged I agree that the walls look a mite thin. But I have never seen a KM before, so I can't tell. Bowl does look coated for sure. But if it has been over reamed, it may or may not have been done by the seller. I have seen LC's in worse shape bring large $, from buyers fully aware of the condition issues. Will a KM be as sought after? Who knows.
To others who might read this thread, I am not really looking for a birth year anything. Thanks for the PM's.
I will say that having owned a few Patent # Post WWII Dunhills, they are among the finest smoking, best fnished pipes I have ever had the privilege of smoking.
