It's a 1963 model. There were 2 models of alto saxophone produced by Conn in 1963. The most common is the 14M Director's model. This saxophone has the shooting star design on the bell. The octave key is mounted on the top side of the neck like most traditional saxophones. Also, there were a few 6M altos made. The 6M has the octave key mounted on the bottom side of the neck. The saxophone would be engraved "6M" on the back near the thumb rest. (Most 14M's were not engraved with the model number.) The earlier 6M's featured a topless lady engraved on the bell in a pentagon along with music notes. The lady disappeared in 1959 I believe, and the later models just had the music notes. I have also seen later 6M's with floral engraving similar to some of the Selmer horns of the time, and 6M's with very little engraving at all. The 6M's are worth more; especially the older (pre 1948) ones. A 1963 6M in good condition would be worth $900-$1100. A 14M director's model in good condition would be worth $450-$600.
