Buffet Crampon S1 clarinet
MRO Saxophones performed a series of Buffet Crampon clarinet overhauls and maintenance checks early 2022, including two S1 models. The S1 is a rather uncommon version and not that many were made during the 1970´s. The first one is an early one from 1974, and the second one is a late one from 1980. I notices some important differences between these S1 clarinets, and couldn´t find any info online on these differences. Both clarinets have the ´F´-prefix and were made for the European market.
