Can anyone help me Identify a Conn Alto Sax that has the serial #M176503 with an A above and an L below the #. It also has 1119954 above the Serial #, and patented Dec 08, 1914 above that.
That's a 1926 Conn New Wonder Series II alto saxophone. These are also referred to as the Chu Berry horns. Leon Chu Berry was a tenor player during the 30's who played a similar model tenor.
