Evette et Schaeffer 1915
One of the main concurrents of Adolphe Sax during the XIXth century was Buffet-Crampon. It was briefly renamed Evette et Schaeffer at the turn of the XXth century (after the names of the genders of the original founders).
The bell engraving is reversed on Adolphe Sax and Evette (probably because of the position of the low Bb key on this last instrument).
This bare brass saxophone dating from 1915, in a remarkable conservation state, doesn’t possess the automatic octave key mechanism yet, though it had been invented since a few years. Its ergonomy is near to XIXth century instruments, but its tube is already of modern conception (similar to the 1928 Buescher).
