Conn "New Wonder II" ca. 1927 Alto Saxophone

From the 1930 Conn General Band Instrument Catalogue:

In orchestras or bands, on the stage of in the ballroom, over the radio or in the orchestra pit, there you will find this superb instrument playing a leading role. It is truly the King of Saxophones. The Eb alto is one of the original saxophones invented by Sax, but the alto, as made today by Conn, far surpasses the original model, due to fundamental improvements in design, bore, tone hole location and key mechanism. Among these improvements are the Hydraulic Expansion Process which insures a glassy-smooth inside surface, tone hole sockets pulled integral from the body metal and rolled, improved pads and knurled tuning device. These are exclusive Conn improvements and are found on no other saxophone. That is why the Conn alto saxophone is the choice of a host of the world's greatest saxophone artists.

You could take Conn's world for it and say this is the greatest saxophone to be created. Or you could come down, play this beautiful horn and see for yourself.
