Nor, from what I understand are they allowed on Shop Night Specials. I have a beautiful Series I love that is ALL Alembic but since it did not officially come from the company, it does not have a logo.I do have an Alembic logo in silver that seems authentic which was given to me by the spouse of an Alembic player who passed away in an accident about a decade ago when I purchased his SC standard. It has no prongs on the back and came on a chain so I’ve always assumed it was made as a piece of jewelry. I have no idea as to the provenance.
