professor o. colletto super swing alto saxophone mouthpiece in real good condition.this is a really rare alto saxophone mouthpiece,made in Italy.it has no bite marks and the rails are clean with no nicks to the brass. the 7# is even more rare and very hard to find.it was designed for jazz and is probably one of the best jazz mouthpieces you will find.especially the #7 with a medium to large bore and great projection.this piece is in great condition and the one screw slide ligature is in great condition too and is not stripped.check out my other listings and many more coming because I am in retirement now and I will be listing many more vintage woodwind & brass instruments & mouthpieces.
