The brand belongs to craftsman Bruto Sordini; today's logo has been used since 2000. Pipes are divided into three grades — rustic, smooth, and straight grain — and rated within each grade with one to three musical notes; the very top examples carry the "Chorale" stamp. Dating has used a numeric stamp since 2002: in 2002, "50/2" gave the craftsman's age together with his years in pipemaking; from 2004 onward, a single number increasing each year was used; no stamp was used in 2003.
