I think I've owned three Cavicchi smooth, most notably a 3C billiard with a long shank and tapered bit. I don't have a name for the shank/bit configuration, but had the stem been a saddle I would have said a lovat. Great pipes with a comparatively low price. Your 5C is a beauty given the grain, especially as it holds on the shank, and the S-curved shank and stem, which I find graceful.
I wondered why he sold his pipes for less, and along the way heard that he uses pre-formed stems, which, if it is the case, would seem to me require some amount of work in the reverse of what we commonly know pipe makers to do. That is, does he decide what shapes he wants to make so that he knows the specifications to specify for the stems that he will order? Does he just order them generally and shape the stummel according to the stem in hand? If the latter, does he have to reject a stem that he had planned to use because in the shaping he discovers a pit, forcing him to go with a secondary shape?
This gets complex, and it could well be that I'm ignoring a simpler explanation. Whatever the answer, Cavicchi has been making pipes for some time and seems to have prospered selling them for less.
