Paul A. sent me a photo of his alto sax in response to my previous post on a saxophone with two octave keys. His saxophone also has two octave keys, and it has a short bell. Contemporary saxophones have a longer bell, go down to B flat, and have two large pads on the bell. Paul’s saxophone has a shorter bell, only goes down to B, and only has one pad on the bell.
Here’s a closeup of the octave keys.
Paul says he found his instrument in an antique shop. It has no serial number or manufacturer information. If you know anything about this model, please leave a comment below.
