Nice to see one of these going for a fair price. A few sellers on eBay get one of these in their hands and they think they’re sitting on a small fortune.
The wood may swell around the tenon after it’s smoked for a bit. If I don’t smoke mine for a while, they’ll loosen up. A dab of carnauba wax and a few smokes takes care of the problem. Plus you may be able to find some old diamond shanked cobs that are in poor shape for cheap and cannibalize the stems. Also be sure to check for pin holes that may leak air in the shank/bowl transistion. A little Elmer’s will fix that. Good smokes!
