I just purchased a Conn 10m tenor sax which plays fantastic. The serial number is 979xxx which does not show up in any charts. The body is like a lady face but it has the under slung octave and the artist not lady on the bell. Notice the wire guards, bell brace, small pearls including thumb rest. It is silver and gold. I have had early RTH 6Ms, Chu Berry tenor and late 1960’s non wire guard 10m and 6m’s. It’s action is fast like early M ladies. Tone is right on and bold when pushed just like the good Conns. The owner could tell me very little on the history. Any thoughts on this one off special saxophone.
