Here is what I believe to be a New York Meyer Alto mouthpiece 5M. There is no writing visible where it would normally say either Made in Usa or New York usa. The Meyer diamond on the facing is still faintly visible enough to distinguish it as a 5M. I own both a New York Meyer and a newer made in Usa for comparison and the shape of this piece is exactly the same as my new york and also plays with a more detailed rich sound similar to my New York.
