Was given this old Poole & Smythe Ltd. Magnum canadian-shape 845 (which the internet informs me was possibly a Dunhill second label?). Has a large crack in the front of the bowl, which goes all the way through. I presume this is unfixable--but I really don't know. I have heard people have put shattered pipes back together... Nice silver band, PSL on the stem.. neat pipe (save the crack). Can this be fixed to make it properly smokeable?
