36 (2000-) Edition Limitée (2014–2015) Axos (2015-) Supreme (2021-) Clarinets—Paris no model name, often called "Breveté" (1900s, 1910s and 1920s) no model name, often called "Déposé" (1930s, 1940s and 1950s) These are often differentiated by the letter at the beginning of the serial number and referred to as "K-series", "L-series", "M-series" or "N-series". A "Déposé" from the N-series will have characteristics very different from those of one from the K-series. The Breveté mark and the Déposé mark were never meant to describe or label the clarinet; they are just French terms meaning, roughly, "certified" and "registered", respectively.

In the December 1999 issue of The Clarinet, Gigliotti wrote: "The first time I went to the Buffet Crampon factory in France was in 1953 and I remember trying 55 Bb clarinets. After selecting the two best ones I then spent countless hours with Hans Moennig tuning and voicing them until I could finally try them in the orchestra. My reason for becoming involved with the Selmer Company was to make it possible for a student or professional to buy an instrument that didn't need all that work and it has resulted in the series 10G which was based on my Moennigized Buffet which I played for 27 years." (Not an exact copy of Buffet acoustically: smaller bore size, more undercutting to tone holes, tone hole placement different, with Moennig's reverse-taper barrel standard
