Now my bad luck with Dunhills never seems end ,this is now second time I have caused a hairline crack to Dunhill Shell Briar shank, First time it was canadian model with very thin shank walls and this time around it was my recently acquired Estate Shell Dunhill from 70ies, one brisk twist when I was removing the stem for cleaning and I'm hearing that familiar dreary sound, hairline crack ! ,Off it goes for banding to Northern Briars England,hope Mr I Walker can handle the task ,needless to say resale value went down the drain,very ''ssed with my carelessness
