I could be totally off base, but the way most pipe company collaborations work is that the artist designs the pipe and then the company makes and markets the pipe. If Tom had of made this by hand, then what was Stanwell's part in this?
I have several pipes designed by artists but made and marketed by a company, such as my three Barbi/Hilson pipes.
But, all in all, it is a step aside from what I normally associate with an Eltang shape, which makes it even more interesting, IMO... whether he designed it or made it himself.
Great pipe! May she squeeze every drop of flavor from the tobacco for you.
