Murder most foul! Indeed! What sort of violent individual does a thing like that? That's about as spiteful as it gets. I'm sending you a PM, and if you like, a couple of pipes to replace your deceased companions. As far as the perpetrator goes, the fleas of 1000 camels infesting his armpits would not be sufficient punishment. Quite frankly, if anyone did something like that to my pipes, that would terminate the relationship with that person. Not because the pipes are so valuable, though indeed some of them are, but because I don't associate with spiteful or vile people, and this would bring an end to the relationship. YMMV.
