My guess is that it wasn't really that good of briar which is why the rustication is so heavy. I'm also guessing that this pipe was made purely for the novelty pipe collector, and not actually intended to smoke. If it was really good briar then I imagine they would have made a couple pipes from that block.I'd say it's a waste of good briar.
Not rare, if you know where to get them, just really expensive.Anyone know how rare are the blocks of briar that would be big enough for such a beast?
