Ralph Morgan Excalibur Alto Saxophone Mouthpiece 7E. The serial number has worn off. (Please check the photos) I purchased it used 15 years ago. It has been refaced. It's very easy to play. It has a mellow sound with a good edge, I think it's a very good mouthpiece. (I used Rico Jazz Select 3S reeds) I was considering keeping it, but I have another mouthpiece that I use as my main one, and this one was a bit too slim for me, so I've decided to sell it. Since it's an old item, please understand that it's non-refundable and non-returnable. Thank you.
