Ash, those are some rare, old and interesting looking pipes, I assume each of those pipes came with the fitted case shown (except as mentioned), but I wonder who makes them (the cases)? Is there anyone out there these days who can make a case like that for a pipe? That would be an interesting thing to try to learn to do.
I would assume one takes a mold of some kind of the pipe, then cuts it in half, splits it, etc., then lines/upholsters it; would be interesting to read someone's write up who has experience in how they are done.
