Beuatiful early Buffet Crampon SA 18-20. Looking at the model. i think it is from the 30’s. Saxpics.com thinks the 40’s http://www.saxpics.com/?v=mod&modID=33 Anyway, it is a silverplated saxophone in a very good condition. It has been extenditely serviced, but not completely overhauled: the pads are still in a superb condition.
