Hi, my roommate came with this sax i try to find the carving (Tosca) on internet but found only Buffet Crampon Tosca clarinets no saxophones with Tosca carving. Sax dont have any other emblem, only s.n., so i would like to know if it has some value and who made it or something more about it.. Please help Thank you.
