Sax_Maniac is correct with the above information. The only thing I have to add, with the info you have provided, is that most Wurlitzers were made by Conn and Buescher. I have several Conn Stencil Wurlitzer C-Melodies, all Silver plate with VERY elaborate hand engraving. I find some of the Wurlitzer model horns to be some of the best stencil horns that both Conn and Buescher ever produced. Hang on to it: The C-melody is making a come back in popularity among Saxophone enthusiasts and collectors of late, and when an appropriate mouthpiece/setup is used, they can be quite fun to play. They also make a great first time repad and overhaul project horn for the would be sax tech. Mike.
