This is very nice early Selmer Airflow mouthpiece. It has the different scroll marking on the shank with the B table. The tip measures 0.054", so it would need to be refaced to be a usable mouthpiece but the tip and rails are in excellent condition.
Here is a Yamaha G1 neck in very good condition. It shows signs of some use with a few minor dings and scratches, but these don't affect the play at all. This is an excellent neck if you need one for your Yamaha 62 or Custom Z!
