This is a sweet vintage C. G. Conn curved soprano saxophone, serial number 206855.
The silver plating on this beauty is nearly immaculate, over 99% intact, with no major wear of note. The sax has a matte silver body and burnished (shiny) silver keys. It does have rolled tone holes and a fingernail file G#. Unlike many vintage curved sopranos, it does feature keywork to high F rather than just high Eb.
There are no major dents or dings anywhere in the sax, and no resoldered joints. This soprano plays with a gorgeous warm rich texture, very sonorous and quite beautiful. It is a joy to play.
