I recently purchased a Dunhill on eBay that is really nice, the only problem is, for some reason the bowl is full of cracks. It has been reamed back to briar so I know it isn't in the cake. One may even go through the bottom of the bowl and show slightly on the underside of the pipe. None of these cracks were listed on eBay, and I wrote the seller and let them know the problems, and they offered me a 50% discount. I don't want to rip them off, or be ripped off myself (I know these cracks are a threat for burnout), so I told them I would ask on this forum what would be a reasonable settlement. I know that adding a layer of pipe mud to the inside is probably the first step, but I am not experienced nor do I have the expendable funds at the moment to ship this out to a pro. Advice is very much appreciated. Thank you!
