Kyle, I have one of these in my collection, and I think it is a really great design. So much so, that I am curious as to why no one has decided to market a similar version, as the cob inserts would be much cheaper if they were currently being produced.
I like the fact that if you only wanted to take one pipe along for a trip, this one would function wonderfully. You could pick three different blends, take along a three pack of bowls, and you would be set. For cleaning purposes, you really don't need any alcohol except for a periodic thorough cleaning. All that is needed is to remove the bowl, and wipe out the interior of the aluminum shell with a paper towel and run a pipe cleaner thru the stem. I also like the fact that the bowls are left in their natural condition, with no plaster added to the exterior, which allows the cob to dry from outside as well as inside. Burnouts aren't much of a problem, as there is a metal insert disc added to each cob insert.
Negatives, are that the pipe is designed for filters, which some folks won't appreciate, but since there's so much less natural material in this design to absorb moisture compared to a traditional cob, the filter is a very functional addition. Also, because of the design of the cob insert, it may be difficult to use pipe mud, given that the draft hole is right in the center of the cob insert. Another negative is the cost of the replacement bowls, which usually go for around $7 to $10 each, but given the fact that a new cob pipe is similar in price, it doesn't make the inserts insane for someone who really likes the design of this pipe. Another negative is bowl capacity, but if you limit your tobaccos to flake varieties, you can offset that negative.
I can see this being a perfect pipe to take on the road for an extended period, which would keep your space savings to a minimum, and still allow you to have the equivalent of 3 dedicated pipes for 3 different blends, or at the least one bowl for English blends, one for Oriental's, and another for Virginia's.
I really wish Missouri Meerschaum would come out with their own version of this pipe, especially now that the larger cobs are in such short supply.
