Serial #K21632, for Guy Y. It looks from the serial number page shown on the top Evette&Schaeffer page that this would predate 1952.
Bore LH joint top: 14.6mm
Bore LH joint at bottom: 14.6mm
On the same day as I tested this, I also tested an Evette Master Model. I found that the Evette Schaeffer was significantly better than the Evette Master Model.
Intonation results taken when playing loud and not lipping. See how to interpret these results on the Model Comparison Page.
For this test, I used my Ridenour 63.4mm barrel and pulled 0 at the barrel, and 0 in the center for this horn.
Intonation summary: Excellent.
Key work quality: Just like Buffet’s top chrome plated models.
This clarinet is most appropriate for: Anyone, intermediate to advanced
