I just got back from long term loan my Buffet Crampon baritone, which seems to be a transitional model between the SDA and the S-1. The engraving on the bell doesn't mention either model by name and neither is it marked on the back of the body tube.
I wanted to check the serial number against some lists to get an idea of when it was made, but I just can't find a number in any of the usual places.
Where should I be looking ?
