Clearly, they are. Since that isn't really what it is, though, I wonder what the seller really knows about the instrument. Maybe I'm a bit of an Alembic snob, but I like to think that most owners spend that much money because they know what they are buying. When someone misrepresents the details of an expensive instrument, it always makes me wonder how they came to own it. Maybe I'm a bit cynical, but I like to think of it as careful.
